  Hereinafter, embodiments will be described with reference to the drawings. In the following description, about the same function and component, the same code | symbol is attached | subjected. Moreover, it is not essential that each functional block is distinguished as in the following example. For example, some functions may be executed by a functional block different from the illustrated functional block. Furthermore, the illustrated functional block may be divided into smaller functional sub-blocks.

(First embodiment)
FIG. 1 is a block diagram illustrating the configuration of the game system according to the present embodiment.
The game system includes a first wireless storage device 1005, a first communication device (toy) 1015, a first accessory 1520, a second wireless storage device 1510, a second communication device (toy) 1017, and a second accessory 1525. A third communication device 1019, a base station 1530, and a server 1535. For convenience of explanation, the game system of the present embodiment will be described as including two communication devices 1015 and 1017. However, the game system is not limited to two, and the game system may include four or ten communication devices, for example. Good.
Since each element will be described in detail later, only the communication relationship and its outline will be described here.

  The first wireless storage device 1005 is, for example, a memory card having a wireless communication function. The wireless communication function is an arbitrary wireless communication function such as a wireless LAN or NFC (Near Field Communication). The first wireless storage device 1005 can communicate with the first communication device 1015, the second wireless storage device 1510, the third communication device 1019, and the base station 1530.

  The first wireless storage device 1005 can be inserted into the first communication device 1015, for example. When the first wireless storage device 1005 is inserted into the first communication device 1015, the first wireless storage device 1005 is electrically connected to the first communication device 1015 via a connection terminal. As a result, the first wireless storage device 1005 can communicate with the first communication device 1015.

  The first wireless storage device 1005 performs wireless communication with the second wireless storage device 1510, the third communication device 1019, and the base station 1530.

  The first communication device 1015 is, for example, a toy. The first communication device 1015 can bidirectionally communicate with the first accessory 1520 in addition to the first wireless storage device 1005. Note that communication between the first communication device 1015 and the first accessory 1520 is not limited to bidirectional communication. For example, the first communication device 1015 unilaterally reads the code attached to the first accessory 1520 and performs bidirectional communication. You do not have to.

  The first accessory 1520 is an accessory for the first communication device 1015. More specifically, the first accessory 1520 is a key holder, a strap, a medal, a card, or the like. A code is attached to the surface of the first accessory 1520. This code can be read from the first communication device 1015.

  The third communication device 1019 is, for example, a smartphone. The third communication device 1019 can communicate with the first wireless storage device 1005 via wireless communication.

  The base station 1530 is a communication terminal disposed in, for example, a shopping mall, an electric shop, a toy shop, or the like. The base station 1530 is, for example, a station or a spot. The base station 1530 communicates with the first wireless storage device 1005 via wireless communication. The base station 1530 communicates with the server 1535 via wireless communication or wired communication.

  The server 1535 performs processing in response to a request from the base station 1530. The server 1535 saves data.

  The second wireless storage device 1510 is, for example, a memory card having a wireless communication function, like the first wireless storage device 1005. The second wireless storage device 1510 can communicate with the second communication device 1017 in addition to the first wireless storage device 1005.

  The second communication device 1017 has the same configuration and function as the first communication device 1015. The second communication device 1017 can communicate with the second accessory 1525 in addition to the second wireless storage device 1510.

  The first communication device 1015 and the second communication device 1017 do not have to be the same type. For example, the first communication device 1015 and the second communication device 1017 may be the same type of toy and may have different product numbers. Alternatively, they may be different types of toys (for example, a key ring-shaped toy and a watch-shaped toy). Alternatively, one may be an app on a smartphone and the other may be a watch-shaped toy.

  The second accessory 1525 has the same configuration and function as the first accessory 1520. Note that, similarly to the relationship between the first communication device 1015 and the second communication device 1017, the first accessory 1520 and the second accessory 1525 do not have to be the same type.

(About the first wireless storage device 1005)
FIG. 2 is a block diagram showing the configuration of the first wireless storage device 1005 according to the present embodiment and the correlation between the first communication device 1015, the second wireless storage device, the third communication device, and the base station that are the periphery thereof. . Note that the operation method and the like of the first wireless storage device 1005 will be described later in detail, so that each element will be described here.

  The first wireless storage device 1005 transmits and receives data and commands to and from the first communication device 1015 according to, for example, an SD interface, but other interfaces may be used. The first wireless storage device 1005 transmits and receives data and commands to and from the third communication device 1019 along the NFC interface, for example, but other wireless communication interfaces may be used.

  The first wireless storage device 1005 includes a first controller 1033, a first wireless antenna 1020, a nonvolatile semiconductor memory 1025, a first NFC controller 1030, a memory controller 1035, and a connection terminal 1065. Note that the first controller 1033, the memory controller 1035, and the first NFC controller 1030 are not necessarily provided separately, and any combination may be provided integrally.

  The first wireless storage device 1005 operates with electric power supplied from the electrically connected first communication device 1015. The first wireless storage device 1005 has a function of writing and reading data.

  Further, at least a part of the first wireless storage device 1005 can be operated by electric power generated (induced) by electromagnetic induction of the first wireless antenna 1020. For example, the first wireless storage device 1005 performs communication according to the near field communication standard (NFC: Near Field Communication) at a frequency such as 13.56 MHz, and the second wireless storage device 1510, the third communication device 1019, the base Data can be written to and read from the station 1530. That is, the first wireless storage device 1005 can operate without receiving power from the first communication device 1015. Note that NFC communication can be performed with lower power than general wireless LAN communication.

  Specifically, the first controller 1033, the memory controller 1035, and the nonvolatile semiconductor memory 1025 operate when the first wireless storage device 1005 is supplied with power from the first communication device 1015. When the first wireless storage device 1005 is only supplied with power via the first wireless antenna 20, the first controller 1033, the memory controller 1035, and the nonvolatile semiconductor memory 1025 do not necessarily operate.

  On the other hand, the first NFC controller 1030 is operable even when the first wireless storage device 1005 is only supplied with power via the first wireless antenna 1020. That is, when the first wireless antenna 1020 receives a radio wave having a predetermined frequency corresponding to NFC, the first NFC controller 1030 becomes operable. That is, the first wireless storage device 1005 can perform NFC communication.

  The first controller 1033 receives a command CMD, an address ADD, and data DAT from the first communication device 1015, the memory controller 1035, and the first NFC controller 1030.

  Based on the received command CMD, the first controller 1033 outputs a command CMD, an address ADD, data DAT, and the like to the memory controller 1035, the first NFC controller 1030, and the first communication device 1015.

  The memory controller 1035 controls the nonvolatile semiconductor memory 1025. The memory controller 1035 writes data to the nonvolatile semiconductor memory 1025 based on, for example, the command CMD input from the first controller 1033. The memory controller 1035 reads data from the nonvolatile semiconductor memory 1025 based on, for example, a command CMD input from the first controller 1033, and outputs the data to the first controller 1033. Further, the memory controller 1035 may communicate with the first NFC controller 1030 and the first communication device 1015 without going through the first controller 1033.

  The nonvolatile semiconductor memory 1025 is, for example, a NAND flash memory, but is a NOR flash memory, an MRAM (Magnetoresitive Random Access Memory), a PRAM (Phase change Random Access Memory), a ReRAM (Resistive Random). Other nonvolatile semiconductor memories such as Access Memory (resistance change type memory) and FeRAM (Ferroelectric Random Access Memory: ferroelectric memory) may be used. For example, the nonvolatile semiconductor memory 1025 may be changed to another nonvolatile memory or the like.

  The nonvolatile semiconductor memory 1025 operates when power is supplied from the first communication device 1015 to the first wireless storage device 1005.

  The first radio antenna 1020 is, for example, a PCB pattern antenna. The frequency band in which the first wireless antenna can operate is set to a predetermined frequency band corresponding to NFC.

  The first wireless antenna 1020 can generate electric power by electromagnetic induction based on radio waves from the third communication device 1019, for example. The first wireless antenna 1020 supplies the generated power to the first NFC controller 1030.

  The first wireless antenna 1020 receives a command CMD, an address ADD, and data DAT from the second wireless storage device 1510, the third communication device 1019, and the base station 1530. The first wireless antenna 1020 outputs the received command CMD or the like to the first NFC controller 1030.

  The first wireless antenna 1020 outputs the command CMD or the like input from the first NFC controller 1030 to the second wireless storage device 1510, the third communication device 1019, and the base station 1530.

  The first NFC controller 1030 includes a first storage unit 1040 and a voltage detector 1045. The first NFC controller 1030 and the first storage unit 1040 may be separated from each other.

  The first controller 1033 receives a command CMD, an address ADD, and data DAT from the first communication device 1015, the memory controller 1035, and the first NFC controller 1030.

  Based on the received command CMD, the first controller 1033 outputs a command CMD, an address ADD, data DAT, and the like to the memory controller 1035, the first NFC controller 1030, and the first communication device 1015.

  The first NFC controller 1030 performs communication with the third communication device 1019 and the like via the first wireless antenna 1020.

  The first NFC controller 1030 receives a command CMD, an address ADD, data DAT, and the like from the first controller 1033 and the first wireless antenna 1020. The first NFC controller 1030 outputs, for example, data DAT to the first controller 1033 and the first wireless antenna 1020 based on the received command CMD.

  Further, the first NFC controller 1030 reads the data DAT from the first storage unit 1040 based on the received command CMD, address ADD, and the like, and outputs the data DAT to the first controller 1033 and the first wireless antenna 1020.

  Further, the first NFC controller 1030 writes the data DAT to the first storage unit 1040 based on the received command CMD, address ADD, data DAT, and the like.

  The command CMD, address ADD, data DAT, etc. communicated between the first communication device 1015, the first controller 1033, the memory controller 1035, the first NFC controller 1030, the first wireless antenna 1020, etc. are not necessarily in the form. There is no need to match. If the command CMD, the address ADD, and the data DAT are recognizable by both the communicating parties, it is not necessary to formally match the command CMD, the address ADD, the data DAT, and the like when communicating in other portions.

  When the first NFC controller 1030 receives the related data generation command CMD and the data DAT via the first controller 1033 or the first wireless antenna 1020, the first NFC controller 1030 may generate the related data DAT ′ and write it to the first storage unit 1040. .

  Note that the first NFC controller 1030 does not necessarily have a writing function to the third communication device 1019 side. That is, it is not necessary to have a function of writing to an NFC tag or the like outside the first wireless storage device 1005. When the third communication device 1019 writes data to the first storage unit 1040 via the first wireless antenna 1020, the third communication device 1019 may directly write to the first storage unit 1040. That is, the first NFC controller 1030 does not necessarily have to write data to the first storage unit 1040.

  The first storage unit 1040 is, for example, a nonvolatile memory. The first storage unit 1040 stores data according to control by the first NFC controller 1030 or the memory controller 1035. Note that the data storage in the first storage unit 1040 may be temporary. As the first storage unit 1040, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory) is used, but various memories can be used in the same manner as the nonvolatile semiconductor memory 1025.

  Note that the non-volatile memory used for the first storage unit 1040 has lower power consumption per unit capacity than the non-volatile semiconductor memory 1025 in order to be operable with the power supplied from the first wireless antenna 1020. Is preferable. Specifically, a NOR type memory may be used.

  The data stored in the first storage unit 1040 includes, for example, related data of the first wireless storage device 1005 (data stored in the nonvolatile semiconductor memory 1025 (for example, image data, sound data (music data, audio data, etc.)) , Video data, etc.), data related to data stored in the nonvolatile semiconductor memory 1025, data related to the nonvolatile semiconductor memory 1025 and the first wireless storage device 1005), and related to the first communication device 1015 Data, data related to the first accessory 1520 connected to the first communication device 1015, and information on the command CMD received from the first controller 1033, the third communication device 1099, and the like are included.

  A specific example will be described. These are merely examples, and the data stored in the first storage unit 1040 is not limited to these.

  The data related to the image data stored in the nonvolatile semiconductor memory 1025 is, for example, file name data, the first or last part of the image data, or thumbnail image data of the image data, file generation time data, shooting time data , Data ID and the like.

  The data related to the sound data stored in the nonvolatile semiconductor memory 1025 is, for example, file name data, first or last part of the sound data, reproduction time data of the sound data, file generation time data, data ID, etc. It is.

  The data related to the nonvolatile semiconductor memory 1025 is data on the memory capacity of the nonvolatile semiconductor memory 1025, data on the remaining capacity, data on the number of stored files, and the like.

  The data related to the first wireless storage device 1005 includes recognition ID data (an identification number arbitrarily assigned to each first wireless storage device 1005, for example, a unique product ID assigned at the time of manufacture, and the first wireless storage device 1005 later. IDs etc. arbitrarily assigned for each), comments (text data associated with the first wireless storage device 1005 stored in the first wireless storage device 1005 by the user via the first communication device 1015), etc. It is.

  Data related to the first communication device 1015 is recognition ID data of the first communication device 1015, firmware update information of the first communication device 1015, flag information generated based on these information, and the like.

  The data related to the first accessory 1520 is recognition ID data of the first accessory, data included in a code provided in the first accessory, flag information generated from the data, and the like.

  The voltage detector 1045 is electrically connected to the first wireless antenna 1020. The voltage detector 1045 detects the voltage supplied from the first wireless antenna 1020 to the first NFC controller 1030. The voltage detector 45 issues a NFC communication reset command until a predetermined voltage at which the first NFC controller 1030 can operate is reached. The first NFC controller 1030 does not perform NFC communication while receiving this reset command. This reset command can prevent abnormal start-up / operation of communication by NFC. The voltage detector 1045 may output an operable command to the first NFC controller 1030 when the voltage reaches a predetermined voltage. The first NFC controller 1030 performs NFC communication only when an operable command is received.

  The connection terminal 1065 is a standardized connection terminal, for example, and can be connected to the first communication device 1015.

  The first wireless storage device 1005 according to the present embodiment may use, for example, the configuration and operation method described in US Patent Application No. 14/477200, “memory card having a wireless antenna”. This patent application is incorporated herein by reference in its entirety.

FIG. 3 is a schematic plan view showing the front and back surfaces of the first wireless storage device 1005.
As shown in FIG. 3A, the first wireless storage device 1005 has a code 1120 on its surface. The code 1120 can be detected by an imaging unit (CMOS sensor) provided in the third communication device 1019, a code recognition unit provided in the first communication device 1015, or the like.

  The code 1120 is, for example, a two-dimensional code having information in two dimensions in the vertical direction and the horizontal direction. The code 1120 is, for example, a two-dimensional matrix code with black and white dots, as shown in FIG. The code 1120 may be a stack code or a one-dimensional barcode. Further, it may be similar to a character shape.

  The code 1120 is, for example, a seal shape, and may be pasted by the user after purchase or may be pasted at the time of manufacture. The code 1120 may be arranged directly in the case of the first wireless storage device 1005, for example, by printing. Further, the code 1120 may be disposed on both the front surface and the back surface of the first wireless storage device 1005.

  Furthermore, the code 1120 does not need to be directly arranged in the first wireless storage device 1005 and may be arranged indirectly. For example, a case that covers at least a part of the first wireless storage device 1005 may be provided, and the cord 1120 may be disposed on the surface of the case. By providing the case in this manner, the user does not need to recognize the entire first wireless storage device 1005, and therefore, it is possible to improve the feeling of immersion in the first communication device 1015, which is a toy, for example.

  The code 1120 includes information (first information) of the recognition ID of the first wireless storage device 1005, for example. In other words, first information such as a recognition ID is displayed on the outer surface of the first wireless storage device 1005.

  As shown in FIG. 3B, the first wireless storage device 1005 has a plurality of connection terminals 1065 on the back side thereof. The plurality of connection terminals 1065 are arranged along one end side of the first wireless storage device 1005.

  As described above, the first wireless storage device 1005 is, for example, a memory card mounted on one or a common envelope or housing, but includes a part or all of the above-described elements separately. It may be a memory system. For example, the memory system includes a memory module having a memory controller 1035 and a non-volatile semiconductor memory 1025, an NFC module having a first wireless antenna 1020, a first NFC controller 1030, a first storage unit 1040, and a voltage detector 1045; And a controller having one controller 1033. The first controller 1033 is connected to the NFC module through, for example, an SPI interface. The first controller 1033 may be included in, for example, a control unit 1390 included in the first communication device 1015 described later, or may be executed as a program step executed by the control unit 1390.

(About first communication equipment)
FIG. 4 is a schematic block diagram illustrating the configuration of the first communication device (toy) 1015.

  First communication device 1015 includes an accessory holding unit 1310, a code recognition unit 1320, a memory card storage unit 1330, and a speaker 1340. Since the second communication device 1017 may have the same configuration as that of the first communication device 1015, detailed description thereof is omitted.

A memory device such as a memory card can be inserted into the memory card storage unit 1330 from the outside.
For convenience of explanation, the description will be made on the assumption that the first wireless storage device 1005, for example, a memory card mounted with an NFC chip, is already held in the memory card storage unit 1330.

  The accessory holding part 1310 has a function of holding an accessory. The accessory holding part 1310 holds an accessory inserted from the outside, for example. The accessory holding unit 1310 may hold the accessory without being inserted from the outside. For example, the accessory holding part on the link holding the accessory of a key holder may be sufficient. For convenience of explanation, description will be made on the assumption that the first accessory 1520 is already held by the accessory holding portion 1310.

  The first accessory 1520 is, for example, a card on which a character is drawn. For example, one character is drawn on one first accessory 1520. Without being limited to this case, a plurality of characters may be drawn on one first accessory 1520. One first accessory 1520 stores information about the drawn character. The first accessory 1520 stores this information in the form of a code, for example. For example, the first accessory 1520 may include an NFC chip, and such information may be stored in the NFC chip.

  When information about the drawn character is stored as a code, when the accessory is held in the accessory holding unit 1310, the accessory code faces (faces) the code recognition unit 1320.

  The code recognition unit 1320 receives an instruction from the outside, and reads information about the drawn character from the accessory code. Such information is transferred to the memory card. The information regarding the character includes address information to be read from the nonvolatile semiconductor memory included in the memory card.

  The first controller 1033 of the memory card receives information on the character and reads the corresponding information. Specifically, the first controller 1033 outputs a read instruction and address to the memory controller 1035, and the memory controller 1035 reads data from the memory at the address corresponding to the information related to the character and outputs the data to the first controller 1033. The memory card outputs this data to the speaker 1340.

(Operation method of the first wireless storage device)
Hereinafter, an operation example of the first wireless storage device 1005 according to the present embodiment will be described with reference to FIGS. For convenience of explanation, a device that communicates with the first wireless storage device 1005 via the connection terminal 1065 is a first host (first communication device) 1800, and a device that communicates via the first wireless antenna is a second device. The host 1850 is assumed. Any one of the second wireless storage device 1510, the third communication device 1019, and the base station 1530 in FIG. 2 is collectively referred to as the second host 1850, and matters common to each operation example are described in the previous operation example. The description of the contents is omitted in the later operation example without particular notice.

(First operation example)
FIG. 8 is a diagram schematically showing a data flow in the first operation example. FIG. 9 is a diagram illustrating a first operation example as a flowchart.

  In the first operation example, data stored in the nonvolatile semiconductor memory 1025 from the first host 1800 is stored in the first storage unit 1040, and the second host 1850 reads data from the first storage unit 1040.

  In step S8101, the first controller 1033 receives a write command CMD, an address ADD, and data DAT from the first host 1800 via the connection terminal 1065.

  In step S8102, the first controller 1033 outputs a write command CMD, an address ADD, and data DAT to the memory controller 1035. Note that, as described above, the write commands CMD in steps S8101 and S8102 do not have to formally match. The same applies to the address ADD and data DAT. The same applies to the following description unless otherwise specified.

  In step S8103, the memory controller 1035 writes to the nonvolatile semiconductor memory 1025 based on the received command CMD or the like.

  In step S8104, the first controller 1033 outputs a read command CMD and an address ADD to the memory controller 1035.

  In step S8105, the memory controller 1035 reads the data DAT from the nonvolatile semiconductor memory 1025 based on the read command CMD and outputs the data DAT to the first controller.

  In step S 8106, the first controller 1033 outputs the received data DAT, write command CMD, and address ADD to the first NFC controller 1030.

  In step S8107, the first NFC controller 1030 writes the data DAT to the first storage unit 1040 based on the received write command CMD or the like.

  In step S8108, the first NFC controller 1030 receives a read command CMD and an address ADD from the second host 1850 via the first wireless antenna 1020.

  In step S8109, the first NFC controller 1030 reads data DAT from the first storage unit 1040 based on the received read command CMD or the like. The first NFC controller 1030 outputs data DAT to the second host 1850 via the first wireless antenna 1020.

  Note that the above-described procedure is not necessarily performed continuously, and the steps may be separated in time.

(Modification of the first operation example)
Hereinafter, a modification of the first operation example will be described.
The first wireless storage device 1005 can operate only by supplying power from the second host 1850 via the first wireless antenna 1020 in steps S8107 to S8109 of the above operation example.

  After step S8103, after input of a command or the like from the second host 1850, step S8104 and subsequent steps may be processed. In this case, only the data required by the second host 1850 can be moved from the nonvolatile semiconductor memory 1025 to the first storage unit 1040. In this case, step S8108 may be omitted.

(About data stored in the first storage unit)
In this operation example, the data DAT written in step S8106 and step S8107 (referred to here as DAT2 for convenience) does not necessarily need to match the data DAT written here in step S8103 (referred to as DAT1 here for convenience). That is, the data stored in the nonvolatile semiconductor memory 1025 and the data stored in the first storage unit 1040 do not need to match. This is the same in the following operation examples.

  For example, DAT2 may be a part of DAT1. DAT2 may be data obtained by processing DAT1 data. For example, when DAT1 is image data, DAT2 may be image data obtained by compressing DAT1, and when DAT2 is sound data, DAT2 may be a more compressed sound or the sound at the beginning. It may be data.

  DAT2 may be data not necessarily directly related to DAT1. For example, when DAT1 is the recognition ID of the first accessory 1520, the DAT2 may be only information on the type of the first accessory 1520. More specifically, when the first accessory 1520 is a “flame sword” key holder, DAT 1 is an individual manufacturing ID corresponding to this key holder, and DAT 2 corresponds to “flame sword”. It may be flag information (information that the fire sword is owned).

  In another example, if the first accessory 1520 is a card of a monster and DAT1 is sound data or a card ID corresponding to the monster, for example, DAT2 is flag information corresponding to the monster. (Information that the monster card is owned) may be used.

  Further, in another example, when DAT1 is position information on the earth corresponding to GPS, flag information that DAT2 has passed a location corresponding to the GPS (for example, a passing point on the game). It may be.

  Thus, the data stored in the nonvolatile semiconductor memory 1025 and the data stored in the first storage unit 1040 do not necessarily match. As a specific example of a method for extracting data stored in the first storage unit 1040, three methods will be described.

  First, as a first method, the first host 1800 outputs a special command CMD, an address ADD, data DAT, and the like to the first controller 1033. In this method, which data is transferred to the first storage unit 1040 is specified by the address ADD and the data DAT.

  The first controller 1033 reads specified data from the nonvolatile semiconductor memory 1025 using the memory controller 1035. Further, the first controller 1033 outputs the read data to the first NFC controller 1030, and writes the data to the first storage unit 1040 using the first NFC controller. This method can transfer data as the user intends.

  Next, as a second method, a setting file is stored in the nonvolatile semiconductor memory 1025 in advance. In the case of this method, when the non-volatile semiconductor memory 1025 can be driven (for example, when the first wireless storage device 1005 receives power supply from the first host 1800), the first controller 1033 has the memory controller 1035. To read the configuration file. Then, the first controller 1033 transmits data to the first storage unit 1040 based on the read setting file.

The setting file includes, for example, a file name (eg, initials start with a specific character), extension (eg, specific extension), date order (eg, 10 from the newest), flag information only, etc. One or more of these various conditions are set. Then, the first controller 1033 writes data that satisfies the condition into the first storage unit 1040 using the first NFC controller 1030. It should be noted that the first controller 1033 may write only the changed portion in the first storage unit 1040, or may rewrite the whole every time.
Note that a method for reading data from the nonvolatile semiconductor memory 1025 and saving the data in the first storage unit 1040 is the same as the first method, and thus the description thereof is omitted.

  Furthermore, as a third method, the setting file may be stored in the first storage unit 1040. In this case, the setting file can be written even when power is supplied only from the second host 1850.

When receiving power supply from the first host 1800, the first controller 1033 reads the setting file from the first storage unit 1040. At this time, the first controller 1033 may store the setting file in the nonvolatile semiconductor memory 1025.
Since the subsequent flow is the same as in the second method, the description is omitted.

  As described above, various methods can be used for extracting data stored in the first storage unit 1040. Of course, the above three methods are not intended to limit the extraction method to these methods.

  In step S8604, the memory controller 1035 writes data to the nonvolatile semiconductor memory 1025 based on the write command CMD or the like.

  In step S8605, the first controller 1033 receives a read command CMD and an address ADD from the first host 1800 via the connection terminal 1065.

  In step S8606, the first controller 1033 outputs a read command CMD and an address ADD to the memory controller 1035.

  In step S8607, the memory controller 1035 reads data from the nonvolatile semiconductor memory 1025 based on the read command CMD or the like. The memory controller 1035 outputs data to the first controller 1033.

(Modification of sixth operation example)
Hereinafter, a modification of the sixth operation example will be described.
In step S8607, the memory controller 1035 may directly output to the first host 1800. That is, the memory controller 1035 may output directly to the first host 1800 via the connection terminal 1065.

(Seventh operation example)
FIG. 20 is a diagram schematically illustrating a data flow in the seventh operation example.
The seventh operation example is an operation in which the first host 1800 and the second host 1850 communicate via the first wireless storage device 1005.

  The first host 1800 can communicate with the first wireless storage device 1005 via the connection terminal 1065. The second host 1850 can communicate with the first wireless storage device 1005 via the first wireless antenna 1020. In addition, communication with the first controller 1033 and the first NFC controller 1030 is possible between the connection terminal 1065 and the first wireless antenna 1020.

  That is, the first host 1800 can communicate with the second host 1850 via the first wireless storage device 1005. Note that the first wireless storage device 1005 may be completely passed through, or a part of the command CMD, address ADD, data DAT, etc. may be converted.

  By using the seventh operation example, the first communication device 1015 can communicate with the base station 1530 by NFC communication via the first wireless storage device 1005. That is, although the first communication device 1015 itself does not have the NFC communication function, the first communication device 1015 can perform NFC communication with the base station 1530 by using the seventh operation example.

  FIGS. 21 to 27 are timing charts schematically showing time series of commands and data in the first operation example to the seventh operation example, respectively. The circled numbers shown in each timing chart have the following meanings for convenience. That is, for the number X in the higher order of XY, when X = 1, it indicates that the command CMD is transmitted and received between the first host 1800 and the first controller 1033. In the case of X = 2, it indicates that the command CMD is transmitted and received between the first controller 1033 and the nonvolatile semiconductor memory 1025. When X = 3, this indicates that command CMD is transmitted and received between the first controller 1033 and the first storage unit 1040. When X = 4, this indicates that command CMD is transmitted and received between the first storage unit 1040 and the second host 1850. When X = 5, it indicates that the command CMD is transmitted and received between the first host 1800 and the first storage unit 1040. When X = 6, the command CMD is transmitted / received between the nonvolatile semiconductor memory 1025 and the second host 1850. When X = 7, it indicates that the command CMD is transmitted and received between the second host 1850 and the first controller 1033. When X = 8, it indicates that the command CMD is transmitted and received between the first controller 1033 and the first host 1800. For the lower number Y, if Y = 1, this indicates that the command CMD is a write command (Write). When Y = 2, it indicates that the command CMD is a read command (Read). For example, in the case of “1-1”, the command CMD indicates that writing is executed between the first host 1800 and the first controller 1033.

  As shown in FIG. 21, in the first operation example, first, after the first host 1800 outputs the write command CMD (1-1), data DATA is transmitted to the first controller 1033. The first controller 1033 interprets the command CMD via the memory controller 1035 and writes the data DATA to the nonvolatile semiconductor memory 1025 (2-1). Thereafter, the first controller 1033 outputs the written data DATA through the memory controller 1035 (2-2). The first controller 1033 writes the data DATA to the first storage unit 1040 via the first NFC controller 1030 (3-1). The second host 1850 transmits a read command CMD to the first NFC controller 1030 (4-2), and the first NFC controller 1030 reads data DATA from the first storage unit 1040.

  As shown in FIG. 22, in the second operation example, after the second host 1850 outputs a write command CMD to the first storage unit 1040 (4-1), data DATA is transmitted to the first controller 1033 ( 3-2). The first NFC controller 1030 writes the data DATA to the first storage unit 1040. The first NFC controller 1030 outputs the written data DATA to the first controller 1033. The first controller 1033 writes the data DATA to the nonvolatile semiconductor memory 1025 via the memory controller 1035 (2-1). Subsequently, the first host 1800 transmits a read command CMD to the first controller 1033 (1-2), and the first controller 1033 that has received the read command CMD transfers the data DATA to the non-volatile semiconductor via the memory controller 1035. Read from the memory 1025 (2-2). The first controller 1033 transmits the read data DATA to the first host 1800.

  As shown in FIG. 23, in the third operation example, after the first host 1800 outputs the write command CMD to the first storage unit 1040 (5-1), the data DATA is transmitted to the first controller 1033. The first controller 1033 that has received the data DATA writes the data DATA to the first storage unit 1040 via the first NFC controller 1030 (3-1). The second host 1850 transmits a read command CMD to the first NFC controller 1030, and the first NFC controller 1030 reads data DATA from the first storage unit 1040 (4-2).

  As shown in FIG. 24, in the fourth operation example, after the second host 1850 outputs the write command CMD (4-1), the data DATA is transmitted to the first controller 1033. Data DATA is written to the first storage unit 1040 by the first NFC controller 1030. The first host 1800 transmits a read command CMD to the first storage unit 1040 (5-2), and the first controller 1033 reads the data DATA from the first storage unit 1040 via the first NFC controller 1030 ( 3-2). The read data DATA is transmitted to the first host 1800 by the first controller 1033.

  As shown in FIG. 25, in the fifth operation example, the first host 1800 outputs a write command CMD to the first controller 1033 (1-1). The command at this time is a through write command for passing through the writing to the first storage unit 1040. The first controller 1033 that has received the data DATA writes the data DATA to the nonvolatile semiconductor memory 1025 via the memory controller 1035 (2-1). The second host 1850 transmits a read command CMD to the nonvolatile semiconductor memory 1025 (6-2). The read command at this time is a through read command that passes through the reading from the first storage unit 1040. The first controller 1033 reads data DATA from the nonvolatile semiconductor memory 1025 by a through read command (2-2).

  As shown in FIG. 26, in the sixth operation example, the second host 1850 transmits a write command to the nonvolatile semiconductor memory 1025 and transmits data DATA (6-1). The first controller 1033 writes the transmitted data DATA to the nonvolatile semiconductor memory 1025 via the memory controller 1035 (2-1).

The first controller 1033 transmits the transmitted data DATA to the first host 1800 based on either the write command or the read command (8-1 or 8-2). Note that the command of the first controller 1033 at this time may be either a write command or a read command, or may be a command arbitrarily set by the user.

  FIG. 28 is a table summarizing the above-described operation example of the first wireless storage device 1005 and its advantages. Each arrow indicates the flow of data, and the hatched area indicates a state in which operation is possible in a state where power is supplied from the first host 1800 side. Note that the non-volatile semiconductor memory 1025 and the first storage unit 1040 can hold data only when data is not held from the first host side.

  As shown in the first row of FIG. 28, in the first operation example, data transfer from the first host 1800 to the second host 1850 is performed by writing to the nonvolatile semiconductor memory 1025 and the first storage unit 1040 and This is done via reading. In the first operation example, data transmission from the first storage unit 1040 to the second host 1850 is performed by NFC communication. Therefore, even if no power is supplied from the first host 1800, the second host 1850 Data can be acquired from the first storage unit 1040.

  As shown in the second row of FIG. 28, in the second operation example, data transfer from the second host 1850 to the first host 1800 is performed by writing to the first storage unit 1040 and the nonvolatile semiconductor memory 1025. This is done via reading. Similar to the first operation example, data transfer between the first storage unit 1040 and the second host 1850 is performed by NFC communication, and thus can be executed without power supply from the first host 1800. is there.

  As shown in the third and fourth lines in FIG. 28, in the third and fourth operation examples, the data transfer between the first storage unit 1040 and the second host 1850 is NFC. Since it is performed by communication, it is executed without power supply from the first host.

  As shown in the fifth row and the sixth row in FIG. 28, in the fifth operation example and the sixth operation example, the data in the nonvolatile semiconductor memory 1025 is not performed without writing to and reading from the first storage unit 1040. Therefore, a large amount of data can be transferred.

  As shown in the seventh line of FIG. 28, in the seventh operation example, data transfer between the first host 1800 and the second host 1850 can be performed directly, so that the nonvolatile semiconductor memory 1025 and Data transfer can be performed without being limited by the data capacity of the first storage unit 1040.

(Operation of the first embodiment)
Hereinafter, an operation example of the game system according to the present embodiment will be described.

(Case 1)
Case 1 relates to NFC communication between the first communication device (toy) 1015 and the base station 1530. Here, in case 1, the first communication device (toy) 1015 will be described assuming that the first accessory 1520 and the first wireless storage device 1005 are already stored. Further, it is assumed that the storage unit of the first communication device (toy) 1015 holds the recognition ID of the first communication device (toy) 1015.

Case 1 will be described with reference to FIG.
Case 1 is an operation method of the game system when data held in the first wireless storage device 1005 is updated via the base station 1530.

In step S3101, the base station 1530 stores the recognition ID of the first communication device (toy) 1015, the data regarding the remaining capacity of the first wireless storage device 1005, and the first accessory 1520 stored in the first communication device (toy) 1015. A transmission instruction is transmitted to the first communication device (toy) 1015 so as to transmit the corresponding code data.
This transmission instruction is input to the control unit 1390 via the first wireless antenna 1020 of the first wireless storage device 1005.

  In step S3102, control unit 1390 instructs code recognition unit 1320 to determine the code of first accessory 1520. In response to this instruction, the code recognition unit 1320 reads the code data of the first accessory 1520 and temporarily stores it in the storage unit of the control unit 1390 (S3103).

  In step S 3104, control unit 1390 transmits a transmission instruction to first wireless storage device 1005 so as to transmit data related to the remaining capacity of the nonvolatile semiconductor memory of first wireless storage device 1005 to control unit 1390. The first controller 1033 of the first wireless storage device 1005 accesses the management area of the nonvolatile semiconductor memory via the memory controller 1035. In this management area, data relating to the recognition ID of the first wireless storage device 1005, the capacity of the first wireless storage device 1005, and the remaining capacity are stored.

  The first wireless storage device 1005 transmits data related to the remaining capacity of the nonvolatile semiconductor memory to the first controller 1033 to the control unit 1390, and the control unit 1390 temporarily stores the data related to the remaining capacity in the storage unit ( S3105).

  The control unit 1390 includes a recognition ID of the first communication device (toy) 1015, data regarding the remaining capacity of the first wireless storage device 1005, and code data corresponding to the first accessory 1520 stored in the first communication device (toy) 1015. Is transmitted to the base station 1530 via the first wireless storage device 1005.

  The control unit 1670 of the base station 1530 stores the recognition ID of the first communication device (toy) 1015, data on the remaining capacity of the first wireless storage device 1005, and the first accessory 1520 stored in the first communication device (toy) 1015. Corresponding code data is received, and update data corresponding to the code data is extracted from the storage unit 1650. Here, the storage unit 1650 of the base station 1530 holds a plurality of code data and update data corresponding to each of them in a table format.

  The control unit 1670 calculates the capacity of the extracted update data. Then, the control unit 1670 calculates the remaining capacity from the data regarding the remaining capacity of the first wireless storage device 1005. The control unit 1670 compares the remaining capacity with the update data capacity (step S3106).

  When the remaining capacity of the first wireless storage device 1005 is larger than the capacity of the update data (step S3106, Yes), the control unit 1670 uses the NFC transmission / reception unit 1610 to specify the address for writing the update data and the update data. The data is transmitted to one communication device 1015 (step S3107).

  On the other hand, when the remaining capacity of the first wireless storage device 1005 is smaller than the capacity of the update data (No in step S3106), the control unit 1670 displays that fact on the display unit 1620 (step S3108).

  In step S3109, the first wireless storage device 1005 of the first communication device 1015 receives the update data and the address for writing the update data, and temporarily stores them in the control unit 1390.

  The control unit 1390 controls the first wireless storage device 1005 so as to write the update data to the designated address. As a result, the first wireless storage device 1005 stores the update data corresponding to the code data in the nonvolatile semiconductor memory.

When update data is written to the first wireless storage device 1005, the first wireless storage device 1005 sends a notification of completion of writing update data to the control unit 1390.
Upon receiving this notification, the control unit 1390 sends a notification of the completion of writing update data to the base station 1530 by NFC communication (step S3110).

  Then, the control unit 1670 of the base station 1530 displays on the display 1620 that update data has been written (step S3111).

(Modification 1 of Case 1)
Next, Modification 1 of Case 1 will be described with reference to FIG.
In Case 1, in step S3106, the control unit 1670 compares the remaining capacity with the capacity of the update data. When the remaining capacity of the first wireless storage device 1005 is larger than the capacity of the update data (step S3106, Yes), the control unit 1670 uses the NFC transmission / reception unit 1610 to specify the address for writing the update data and the update data. The data is transmitted to one communication device 1015 (step S3107). Instead of steps S3106 to S3108, the control unit 1670 may transmit flag information data (step S3107 ′).

  Here, the flag information data indicates, for example, communication with a certain base station 1530. Flag information data can be used in place of the stamp rally stamp.

(Modification 2 of Case 1)
In the second modification, the control unit 1670 transmits flag information data. However, the flag information data may be key data for accessing a certain area of the nonvolatile semiconductor memory 1025.
This will be specifically described below.

  Specific data is stored in the nonvolatile semiconductor memory of the first wireless storage device 1005. This particular data is encrypted. The first wireless storage device 1005 of the first communication device 1015 receives key data for decryption from the base station 1530 and decrypts specific data. When the specific data is decrypted, the user can access the specific data.

  In this case, the case where specific data is decoded will be described. However, the present invention is not limited to this case, and the first communication device 1015 and the base station 1530 perform NFC communication, and then the nonvolatile memory of the first wireless storage device 1005 is used. As long as a part of the region of the conductive semiconductor memory 1025 can be used by the user, any mode may be used. For example, the first wireless storage device 1005 has flag information indicating whether or not a part of the nonvolatile semiconductor memory can be accessed. The first wireless storage device 1005 may rewrite the flag information through NFC communication between the first communication device 1015 and the base station 1530, so that the user may be able to access a partial area of the nonvolatile semiconductor memory.

  The control unit 1670 of the base station 1530 transmits the key data to the first communication device 1015 via the NFC transmission / reception unit 1610. The first controller 1033 of the first wireless storage device 1005 receives the key data via the first NFC controller 1030 and holds it on the RAM. The first controller 1033 designates the address of the area where the specific data is held, and reads the specific data on the RAM via the memory controller 1035. The first controller 1033 decrypts specific data based on the key data.

  The first controller 1033 transfers and stores the decrypted specific data at the original address of the nonvolatile semiconductor memory 1025.

  The first controller 1033 notifies the NFC transmission / reception unit 1610 of the base station 1530 that the decoding of the specific data has been completed. When the NFC transmission / reception unit 1610 receives the notification, the control unit 1670 displays a completion message on the display unit 1620.

  In this case 2, the example in which the first communication device 1015 receives one key from one base station 1530 and decrypts the specific data has been described. However, the present invention is not limited to this case. The first communication device 1015 may receive the key data, and the first wireless storage device 1005 may decrypt the specific data using a plurality of keys.

  Further, the nonvolatile semiconductor memory of the first wireless storage device 1005 may have a plurality of areas in which encrypted data is held. The plurality of regions are, for example, region 1, region 2, region 3,. In this case, the first wireless storage device 1005 performs NFC communication with the first base station, receives a key for decrypting the data in the region 1 from the first base station, and is different from the first base station. NFC communication with the second base station may be performed, and a key for decrypting the data in region 2 may be received from the second base station.

(Modification 3 of Case 1)
In Case 1, the base station 1530 transmits the update data and the address for writing the update data to the first communication device 1015. However, the present invention is not limited to this case. For example, the firmware of the first wireless storage device 1005 and the address for writing the firmware are used. May be transmitted instead of the update data and the address to which the update data is written.

(Case 2)
Case 2 relates to NFC communication between the first communication device (toy) 1015 and the base station 1530. Here, in case 2, the first communication device (toy) 1015 will be described assuming that the first accessory 1520 and the first wireless storage device 1005 are already stored. Further, it is assumed that the storage unit of the first communication device (toy) 1015 holds the recognition ID of the first communication device (toy) 1015.

Case 2 will be described with reference to FIG.
First, in step S3201, the control unit 1390 of the first communication device (toy) 1015 instructs the code recognition unit 1320 to determine the code of the first accessory 1520 by an external instruction. In response to this instruction, the code recognition unit 1320 reads the code data of the first accessory 1520 and temporarily stores it in the storage unit of the control unit 1390 (S3202).

  In step S3203, the control unit 1390 controls the first wireless storage device 1005 to temporarily hold the code data and the recognition ID of the first communication device (toy) 1015 in the first wireless storage device 1005. The first wireless storage device 1005 temporarily stores the code data of the first accessory 1520 and the recognition ID of the first communication device (toy) 1015 stored in the first communication device (toy) 1015.

  The control unit 1390 receives the ready signal indicating that the signal can be received from the NFC transmission / reception unit 1610 of the base station 1530 (step S3204), and the base station 1530 receives the code data and the recognition ID of the first communication device (toy) 1015. Is transmitted (step S3205).

  In step S3206, the control unit 1670 receives the code data and the recognition ID of the first communication device (toy) 1015, and transmits these data to the server 1535 via the communication unit 1660. The server 1535 holds a table in which the recognition ID of the first communication device (toy) 1015 is associated with the code data of the first accessory 1520 mounted on the first communication device (toy). The server 1535 also holds a table in which image data, moving image data, and audio data corresponding to code data are associated.

  In step S3207, the control unit 1670 extracts image data and moving image data corresponding to the code data from the server 1535, and displays them on the display unit 1620. The control unit 1670 extracts audio data corresponding to the code data from the server 1535 and outputs the audio data to the speaker 1630.

(Case 3)
In the case 3, when the first communication device (toy) 1015 breaks down for some reason or when the first communication device (toy) 1015 is replaced with a new version, the data is stored in the plurality of first communication devices (toys) 1015. The present invention relates to a communication method in a case where data used in a first communication device (toy) 1015 is moved to another second communication device (toy) 1017 when sharing is desired.

Case 3 will be specifically described with reference to FIG.
In Case 3, the base station 1530 is used to move the data used in the first communication device (toy) 1015 to another second communication device (toy) 1017.

  First, in step S3301, the control unit 1670 of the base station 1530 notifies the first communication device (toy) 1015 that data can be received. Upon receiving this notification via the first wireless storage device 1005, the first communication device (toy) 1015 receives the notification ID of the first communication device (toy) 1015, data in the cache memory 1395 in the control unit 1390, non-volatile Data in the semiconductor memory 1025, the first storage unit 1040, and the like are transmitted to the base station 1530 (step S3302).

  In step S 3304, the server 1535 stores the received recognition ID of the first communication device (toy) 1015, data in the cache memory 1395 in the control unit 1390, and the like.

  In step S <b> 3305, the second communication device (toy) 1510 receives the recognition ID of the second communication device (toy) 1510 and the cache memory 1395 in the control unit 1390 via the second wireless storage device 1510 under user control. Data, data in the nonvolatile semiconductor memory 1025, the first storage unit 1040, and the like are transmitted to the base station 1530.

When the authentication is completed, the server 1535 transmits the data in the cache memory 1395 in the control unit 1390 corresponding to the recognition ID of the first communication device (toy) 1015 to the second communication device (toy) 1510. .

  As a result, the user can use the second communication device (toy) 1510 in the same environment as the first communication device (toy) 1015.

(Case 4)
Case 4 relates to NFC communication between the first communication device 1015 and the base station 1530, and NFC communication between the second communication device 1017 and the base station 1530. Base station 1530 includes a plurality of NFC transmission / reception units 1610. For convenience of explanation, it is assumed that the base station 1530 includes two NFC transmission / reception units 1610. The first NFC transmission / reception unit 1610 performs NFC communication with the first communication device 1015, and the second NFC transmission / reception unit 1610 performs NFC communication with the second communication device 1017.

The first wireless storage device 1005 is the same as that described above, and a detailed description thereof is omitted. The first wireless storage device 1005 is electrically connected to the first communication device 1015. In this embodiment, the first communication device 1015 is, for example, a computer terminal arranged in a store. The first communication device 1015 is electrically connected via the connection terminal 1065 of the first wireless storage device 1005. The first communication device 1015 transfers a plurality of data held by itself to the first wireless storage device 1005, and the first wireless storage device 1005 stores the plurality of data in, for example, the nonvolatile semiconductor memory 1025. doing. Note that the first communication device 1015 only needs to be able to supply power to the first wireless storage unit 1005 via the connection terminal 1065, and instead of the first communication device 1015, the first wireless storage unit 1005 is connected to the first wireless storage unit 1005 by other means. Electric power may be supplied.

  The first wireless storage device 1005 is electrically connected to the second communication device 1019. This connection is a connection by wireless communication. The second communication device 1019 is, for example, a smartphone owned by a store user (customer). The second communication device 1019 is connected via the first wireless antenna 1020 of the first wireless storage device 1005.

  More specifically, as shown in FIG. 42, the memory system of this embodiment includes a memory card that is the first wireless storage device 1005, a computer terminal that is the first communication device 1015 to which the memory card is connected, A smartphone which is the second communication device 1019 that specifies data to be acquired is included. In this example, the terminal computer which is the first communication device 1015 is configured to be USB-powered by a conversion adapter.

  For example, a plurality of data included in the first communication device 1015 is transferred and stored in the nonvolatile semiconductor memory 1025 of the first wireless storage device 1005. In this example, the plurality of data are data of documents in which recipes for daily dishes are described. One data is stored for each date. The plurality of data transferred to the non-volatile semiconductor memory 1025 of the first wireless storage device 1005 does not need to be data that the first communication device 1015 has, and may be data written by another computer terminal or the like. . The first wireless storage device 1005 is connected to the first communication device 1015 and can receive power from the first communication device 1015.

  In this example, the first wireless storage device 1005 and the first communication device 1015 are arranged in a retail store such as a supermarket that sells ingredients for cooking recipes included in a plurality of data.

  A user who visits a retail store or the like where the first wireless storage device 1005 and the first communication device 1015 are arranged has a smartphone that is the second communication device 1019. The user can perform information for acquiring specific data from the plurality of data for the second communication device 1019.

  The user performs information for acquiring specific data to the second communication device 1019 and holds it over the first wireless storage device 1005, thereby establishing a connection between the first wireless storage device 1005 and the second communication device 1019. Is done. The information specified by the second communication device 1019 is transmitted to the first wireless storage device 1005, and the first wireless storage device 1005 acquires data corresponding to the specified information from the nonvolatile semiconductor memory 1025, and Data is transmitted to the second communication device 1019.

  More specifically, it is as follows. That is, as shown in FIG. 43, the first wireless storage device 1005 writes the data transferred from the first communication device (first host) 1015 into the nonvolatile semiconductor memory 1025 (steps S9101, S9102).

  In step S9103, the second communication device (second host) 1019 sets the type of data to be acquired, for example, the current date. After the connection between the second communication device 1019 and the first wireless storage device 1005 is established, the date (April 2) as the specification information is stored in the first storage unit 1040 by the first NFC controller 1030. .

  In step S <b> 9104, the date of the current day (April 2), which is the designation information stored in the first storage unit 1040, is acquired by the first controller 1033.

  In step S 9105, the first controller 1033 reads out data (a document file of the recipe on April 2) corresponding to the date (April 2), which is the designation information, from the nonvolatile semiconductor memory 1025, and It is written in one storage unit 1040.

  In step S 9106, the first NFC controller 1030 transmits the corresponding data (April 2 recipe document file) to the second communication device 1019 via the first wireless antenna 1020.

  As shown in FIG. 44A, a plurality of data is written in the nonvolatile semiconductor memory 1025 in the first wireless storage device 1005. When writing to the nonvolatile semiconductor memory 1025, power is supplied from the host at the time of writing such as the first communication device 1015. If the computer terminal that has written a plurality of data is different from the computer terminal that supplies power to the first wireless storage device 1005 when using the store, the contents of the nonvolatile semiconductor memory 1025 are stored in the computer terminal when using the store. You may set not to overwrite with data. By providing an identification area for prohibiting writing in a specific area of the nonvolatile semiconductor memory 1025, overwriting or the like can be prevented.

  As shown in FIG. 44B, NFC communication is used for transmission of the designation information from the second communication device 1019 (step S9103). Therefore, the first wireless storage device 1005 can transmit and receive data without supplying power from the first communication device 1015.

  As shown in FIG. 44 (c), data matching the specified information can be transferred from the nonvolatile semiconductor memory 1025 to the first storage unit 1040 under the control of the first controller 1033.

  In the memory system of this embodiment, data transfer from the first communication device 1015 to the second communication device 1019 via the first wireless storage device 1005 can be performed according to the procedure of the first operation example. Since this data can be transferred with data that matches part of the specified information, it is possible to transfer to data according to the NFC communication capacity or the storage capacity of the first storage unit 1040. . Moreover, since NFC communication is used for data transfer from the first storage unit 1040 to the second communication device 1019, it is not necessary to supply power to the first wireless storage device 1005. For example, at the store side, the first NFC controller 1030 designates the data by transferring only the data of the day to the first storage unit 1040 with the first wireless storage device 1005 connected to the first communication device 1015. Data matching the information may be transmitted to the second communication device 1019. Therefore, by transferring a small amount of data to the first storage unit 1040 in advance, it is possible to operate the memory system even when there is no power supply from the first communication device 1015.

48A to 48C are schematic block diagrams for explaining the operation of the first wireless storage device of the present embodiment.

  As shown in FIG. 45, the memory system of this embodiment includes a first wireless storage device 1005. The first wireless storage device 1005 is the same as that described above, and a detailed description thereof is omitted. The first wireless storage device 1005 is connected to the base stations 1530, 1531, and 1532. Base stations 1530, 1531 and 1532 have the same configuration as base station 1530 described above. The first wireless storage device 1005 is sequentially connected to each of the plurality of base stations 1530, 1531, 1532. The plurality of base stations 1530, 1531, and 1532 are a station A, a station B, and a station C that are installed at different locations. The number of base stations is not limited, and may be one, two, or four or more. Each base station 1530, 1531, 1532 transmits data to the first wireless storage device 1005 when connected to the first wireless storage device 1005. The data may be any data size that can be stored in the first storage unit 1040, and the type of data is not limited. For example, it may be image data, audio data, text, or simple flag information data. Moreover, these combinations may be sufficient.

  The first wireless storage device 1005 can be electrically connected to the first communication device 1015 via the connection terminal 1065. The first wireless storage device 1005 receives data from the first communication device 1015 when connected to the first communication device 1015. The received data is stored in the nonvolatile semiconductor memory 1025 of the first wireless storage device 1005. The data received by the first wireless storage device 1005 from the first communication device 1015 may be any data size that can be stored in the nonvolatile semiconductor memory 1025, and the type of data is not limited. For example, it may be image data, audio data, text, or simple flag information data. Moreover, these combinations may be sufficient.

  In this example, the first communication device 1015 is connected to the server 1535, but the first communication device 1015 has a sufficient storage capacity that can be stored in the first storage unit 1040, and the first wireless device 1015 If data can be exchanged with the storage device 1005, it may be a stand-alone.

  The first communication device 1015 is a computer terminal or the like disposed in a store, for example. As will be described later, the first communication device 1015 may be combined with each of the base stations 1530, 1531, and 1532. That is, the station A can be connected to the first wireless storage device 1005 by NFC communication to exchange data, and can be connected via the connection terminal 1065. In this example, the base stations 1530, 1531, 1532 and the first communication device 1015 are configured as separate devices, but the base stations 1530, 1531, 1532 and the first communication device 1015 are integrated. You may make it comprise. That is, each NFC communication station may have a memory card interface.

  More specifically, as shown in FIG. 46, in this embodiment, electronic data is used as a circulating mark instead of a stamp. The electronic data is, for example, still image data DATA1, DATA2, DATA3. The plurality of stations store, for example, still image data DATA1, DATA2, and DATA3 of cartoon characters. When the user holds the memory card that is the first wireless storage device 1005 over the station, the NFC communication is used. Any one of the character still image data DATA1, DATA2 and DATA3 can be received. The user who has acquired the still image data DATA1, DATA2, and DATA3 of all the characters through all the stations connects the first wireless storage device 1005 to the first communication device 1015, and thereby the still image data DATA1 of the character. , DATA2 and DATA3 can be received, for example, moving image data. That is, in the memory system according to the present embodiment, a still image data DATA1, DATA2, and DATA3 of characters are collected instead of stamps, and a game system is provided in which a user who collects all of them receives a privilege based on electronic data. Can do.

  More specifically, it is as follows. That is, as shown in FIG. 47, in step S9201, the station A that is the base station 1530 transmits a write command, and then transmits still image data to the first wireless storage device 1005. Flag information is given to each of the still image data DATA1, DATA2, and DATA3, and is transmitted to the first wireless storage device 1005 together with the flag information. When the user acquires all the still image data DATA1, DATA2, and DATA3 and all the flag information is set, specific URL data is written in the first storage unit 1040.

  In step S9202, the first NFC controller 1030 of the first wireless storage device 1005 writes still image data DATA1, DATA2, DATA3 and flag information in the first storage unit 1040.

  In step S9203, the station B, which is another base station 1531, checks whether all flag information data is written in the first storage unit 1040 of the first wireless storage device 1005. When there is unsatisfied flag information, the first wireless storage device 1005 stands by until data that has not been acquired from any of the still image data DATA1, DATA2, and DATA3 is received from the next base station. The base station 1531 does nothing for the first wireless storage device 1005 thereafter.

  If all the contents are written, in step S9204, the first controller 1033 transmits the URL storing the privilege data to the first communication device 1015. The specific URL data may be stored in the first communication device 1015 in advance.

  In step S9205, the URL data is received by the first communication device 1015. In step S9206, the first communication device 1015 accesses the transmitted URL, and stores stored image data (or moving image data) or the like. Get privilege data for content completion.

  In step S9207, privilege data is received by the first controller 1033 of the first wireless storage device 1005 connected to the first communication device 1015 via the connection terminal 1065.

  In step S 9208, privilege data is written into the nonvolatile semiconductor memory 1025 by the first controller 1033.

  As shown in FIG. 48 (a), the first wireless storage device 1005 has the first NFC controller 1030, so that data is written even if power is not supplied from the first communication device 1015 or the like. be able to. Therefore, the user of the first wireless storage device 1005 can carry between stations without having a driving device or the like for driving the first wireless storage device 1005.

  As shown in FIG. 48 (b), the data written in the first storage unit 1040 does not go through the writing to and reading from the nonvolatile semiconductor memory 1025, and is controlled by the first controller 1033. Forward to 1015. The first communication device 1015 can perform processing based on the acquired still image data DATA1, DATA2, DATA3, and the like. For example, encryption processing or the like is performed on the acquired content data, and complicated processing such as encryption decryption processing can be performed when all the content data is aligned.

  As shown in FIG. 48C, the first wireless storage device 1005 can store a large amount of data in the nonvolatile semiconductor memory 1025 from the first communication device 1015 via the connection terminal 1065.

  In the memory system of this embodiment, since the capacity of data transmitted from the base station 1530 to the first wireless storage device 1005 is small, it can be realized without power supply using communication via NFC communication. Moreover, based on the small capacity data acquired via NFC communication, large capacity data can be acquired from the first communication device 1015 via the high-speed network, the connection terminal 1065, or the like. That is, large-capacity data communication can be performed by performing small-capacity data communication. In the above description, for the procedure for acquiring data from the base station 1530 and transferring the data to the first communication device 1015, the fourth operation example described above can be used. When acquiring privilege data, you may make it write data in the 1st memory | storage part 1040 directly via NFC communication. Thereafter, data can be transferred from the first storage unit 1040 to the nonvolatile semiconductor memory 1025 using a computer terminal or the like owned by the user (second operation example). In addition, privilege data is written in the first storage unit 1040 in advance, and when the content data is ready, reading from the first storage unit 1040 is permitted and the data can be transferred to the nonvolatile semiconductor memory 1025 or the like. It may be.

  In the case of a so-called stamp rally, a stamp is pressed on a paper mount to compete for the number of stamps collected. However, since the stamp is pressed against a paper mount, there is no use other than viewing the stamp. In addition, it may compete for whether or not the number of stamps collected has reached a predetermined number, and if the number of stamps reaches a predetermined number, a privilege such as being able to exchange for a prize may be provided. It is necessary to prepare resources for exchanging goods, such as securing a place for storing items and assigning personnel for exchange.

  On the other hand, in the memory system of the present embodiment, the user has a range of usage such as using the acquired electronic data as still image data or the like for decoration for e-mail using his / her own computer terminal or smartphone. Expanding. In some cases, a copy of the acquired still image data can be transmitted to a third party such as a friend. Moreover, since privilege data is also electronic data, uses, such as the above processes and transfer, spread.

  On the other hand, for example, an IC card equipped with an NFC communication function is used to go around a plurality of stations and play a game imitating a stamp rally. In this case, the information of the host connected to the station is updated based on the identification information of the NFC communication of the IC card, and when a predetermined number of stations are visited, it may be exchanged for a prize.

  On the other hand, in the memory system of the present embodiment, the first wireless storage device 1005 has the first storage unit 1040, so it stores still image data DATA1, DATA2, DATA3, etc. acquired by NFC communication, It can be used for applications such as processing and transfer. In addition, since the memory system includes the first controller 1033 and the large-capacity nonvolatile semiconductor memory 1025, the first storage unit 1040 stores large-capacity data different from the still image data DATA1, DATA2, DATA3, and the like. Can be acquired and stored. Therefore, the user can obtain privilege data without exchanging goods or the like.

(Sixth embodiment)
As already described with reference to FIGS. 3A and 3B, the first wireless storage device 1005 of this embodiment is attached to the surface of the envelope in addition to the identification information used in NFC communication. For example, a code 1120 which is a two-dimensional matrix code or the like. When individual identification of the first wireless storage device 1005 is performed, it is possible to select whether to use identification information in NFC communication or to use a code 1120 attached to the surface.

  Identification information for NFC communication is stored in the first storage unit 1040 of the first wireless storage device 1005. The code 1120 is also attached with information including identification information. The user purchases a memory card which is the first wireless storage device 1005. After purchasing the memory card, the user can obtain and retrieve the lottery winning number announced from the URL set by the smartphone which is the second communication device 1019. This winning number is associated with identification information or a part of NFC communication of any memory card. Therefore, the user can acquire the identification information of the NFC communication of the memory card using the NFC communication function of the smartphone, and can confirm whether or not it is associated with the acquired winning number. Instead of the second communication device 1019, for example, by performing NFC communication with the base station 1530 prepared in the store where the first wireless storage device 1005 is purchased, the identification information and the winning number are collated. Also good. Here, even if the smartphone does not have the NFC communication function, identification information for NFC communication can be obtained by photographing the code 1120 using the smartphone camera. By confirming the association between the information of the obtained code 1120 and the winning number, it is possible to know the presence or absence of winning.

  Furthermore, by connecting the memory card having the identification information associated with the winning number to the store computer that is the first communication device 1015 via the connection terminal 1065, the image data is obtained by the steps after step S9204 of the fifth embodiment. It is also possible to acquire winning data such as. Alternatively, winning data may be acquired using NFC communication instead of the first communication device 1015 or using the base station 1530 integrated with the first communication device 1015. When NFC communication is used, winning data may be directly acquired via NFC communication as in the case of the fifth embodiment.

  As described above, the identification information of the NFC communication and the data related thereto are collated by using either the NFC communication or the code 1120 attached to the envelope surface of the first wireless storage device 1005. be able to. Further, by recognizing the identification information of NFC communication on the first communication device 1015 side, large-capacity data transfer between the first communication device 1015 and the first wireless storage device 1005 can be performed.

(Seventh embodiment)
In the memory system of the present embodiment, identification information used in NFC communication and the code 1120 attached to the surface can be used in association with each other to prevent impersonation.

  In NFC communication, when performing data communication, there is a case where processing such as encryption is not performed, so that a malicious other person who generates the same identification information uses this same identification information, There is a risk of impersonating the original owner of the first wireless storage device 1005. Since the first wireless storage device 1005 of this embodiment has a code 1120 associated with this identification information separately from the identification information of NFC communication, by performing authentication using both the identification information and the code 1120, Such impersonation can be prevented.

  For example, the first wireless storage device 1005 is connected to the second communication device (second host, smartphone) 1019 by NFC communication to acquire identification information used for NFC communication. Since the identification information is associated with the code 1120, the code 1120 matches the identification information of the first wireless storage device 1005 by photographing the code 1120 using the camera of the second communication device 1019. It can be confirmed whether or not.
