New description: [New technical field] This creation is about memory devices, especially a memory device with multiple partitions (multi_partition). [Prior Art] With the advancement of information technology, the demand for various kinds of information is exploding. In recent years, many small portable memory devices have become popular, such as a USB flash disk with a flash memory as the main memory medium (USB Flash Disk, commonly known as a USB flash drive or thumb). Brother), and including small size flash memory (CompactFlash, CF), memory stick (Mem〇ry Stick, MS), Secure Digital (SD), multimedia card (Multimedia Card, MMC) special specifications All kinds of flash memory cards of the brand, Micro Hard Disk using CF or USB interface, or even thin type equipped with usb or PCMCIA interface and installed in the external box. Hard Disk, etc. 'satisfy people's desire for r information portability and growth. A conventional portable memory device includes a non-volatile memory array (Non-Volatile Memory Array), a controller (Controller), and an I/O interface. The memory M305380 array is used to store the information that the user wants to transmit, and it must have the characteristics of storing the stored data without external power supply, so the flash memory is often used as the memory. The array, of course, can also be used by hard drives. The control device includes the associated circuitry, interface and drive mechanism needed to drive and access the memory array. This driving mechanism may be in the form of a Hardware Command Sequencer circuit to execute a series of Micro-Code programs, or may be a hardware/micro device. The processor (MiCr〇-Controller/Mic❿Pr〇cess〇r) circuit form exists in the controller of the portable memory device in a manner of executing a series of firmware programs. The transmission interface is based on what kind of communication protocol (Pr〇t〇c〇l) is used to communicate and communicate with the external device (or host). In the memory cards of various specifications, the embedded flash memory array is usually divided into two areas, one is a user area, and the user data is stored. The other is the Secure Area, which is the area where the data required for the memory card specific security agreement (such as the CPRM agreement of the SD card) is stored. The other one is the System Area, which is the firmware required for the controller and related information. In these three areas, the external device can only read and write to the user area using the general read and write instructions specified by the specifications. The data in this area, the user has full access to use, the data slot M305380 stored in the application is stored in this area, there is no guarantee that the data will not be deleted and copied. Although the SD memory card has a protection mechanism such as CPRM, it can provide an application to store the secret # material, but when using cpRM, the content must be encrypted first, and the mine must be used when it is used, and the county has a considerable burden. In addition, there is no portable device that does not support CPRM: direct use. Figure 1 is a schematic illustration of a regional configuration of a flash memory array of the prior art. As shown in the figure, the system includes a system area u, a user area 12, and a secret area 13. The system area n generally stores the physical and related memory data required by the memory card controller. The user area I2 is an area used by the user to access the memory card via the external device, and the size of the user area is the size of the memory card available to the user. Confidential area 13 storage, if the card is generated by the crane, the data in this area can only be accessed by the relative Baolongsi, and (4) the tribute of this area cannot be directly read. For example, the confidentiality agreement adopted by the SD card is CPRM, and the secret area can only access the secret area after using the CPRM instruction and checking the milk controller memory data. Figure 2 is a schematic diagram of a conventional memory card bus arrangement. Memory Cards are not divided into two types: command CMD bus and data DAT bus. The CMD bus has a command envelope including 2 and response packets. The command packet 20 contains a response from the external device to the memory card M3 053 80 ( 〇^and) 〇 Wt30. The DAT busbar has the information of the 4G series including the external device writes or the data from the second device. , a 17 hidden card is taken to read the needle to capture the reading or writing action.

The command parameter 25 includes: a message bit and a padding unit, which constitute a fixed length information booth. A. In the memory card of each Weige, although there are some rules for the health system, there is no consistent definition for multiple partitions. Although the user can use the application software on an external device to cut out multiple partitions, On other different external devices, these multiple partitions may not be accessible, causing various problems. In addition, some specifications may have problems with backward compatible. For example, for the High Capacity card of the SD memory card ν2·0, only the external device of the previous SD version can be read, and the user's use restriction and the M305380 are not available. [New content] Therefore, One of the purposes of this creation is to provide a device with multiple partitions to avoid compatibility problems when accessing different external devices. Another object of the present invention is to provide a memory device with multiple partitions to avoid backtracking compatibility between different specification versions.

The access command is a general read or write command as specified by the support communication protocol, and can perform a read or write operation of a specified logical address. For example, in the 沁 specification, 'CMD17, CMD18, CMD24, and CMD25 are the general read and write commands for which they are regulated. Throughout the user area 511, the external device 54 can only read and write the visible partition through the access command, and other non-visible partitions cannot read and write with the access command. That is, in the multi-partition of the user area 511, only the partition can be seen by ''. The controller 53 is coupled to the transmission interface 52 and the non-volatile memory 51, and can access the visible partition according to the identification information of the visible partition and the access command issued by the external device 54. In one embodiment, the addressing range of the access command corresponds to the capacity of the visible partition. For example, if the visible partition has a capacity of 128M bytes, the access command can specify a logical address range of 0~(128M-1) (assuming each logical address represents a tuple-sized memory space) That is, the specified logical address represents the relative position within the visible partition. In this embodiment, the controller 53 finds the visible partition (ie, the partition 5111) according to the identification information of the visible partition, and converts the logical address specified by the access command into a physical address (physical address). The partition is visible for reading and writing. It is worth noting that the system area 512 cannot be accessed using the general read 12 M305380 write command as specified by the support protocol. However, if the external device 54 can issue a specially designed custom command that is compatible with the support protocol (as will be described later in detail), the data stored in the system area 512 can be updated. In an embodiment, the controller 53 updates the identification information of the visible partition according to the first customized configuration command issued by the external device 54, to switch the visible partition to another partition of the user area 5U, for example, from the area. 5111 switches to partition 5112. In another embodiment, the controller 53 updates the configuration information of the visible partition according to the second customized configuration command issued by the external device 54 to adjust the version of the support protocol. For example, adjust the version from SD vl.Ol to SD v.1.1. In one embodiment, system area 512 includes a plurality of first bays for storing the capacity of each partition of user area 511. The system area 512 also includes a plurality of second blocks for recording the support protocol for each partition. The control state 53 updates the first barriers according to the third custom group sentiment order issued by the external device 54 to adjust the capacity of any of the partitions. The control controller S3 also adjusts the multiple partitions of the user area 511 according to the fourth custom configuration command issued by the external device M. For example, set the capacity of a partition to zero to remove the partition; or add a capacity record as the capacity of the new partition. The controller 53 further updates the second fields in accordance with the fifth custom configuration command issued by the external server 54 to adjust the support protocol of the any-partition. By borrowing _ five-first--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- For different conventional external devices, the visible partition can be accessed; and for the external device that can issue the aforementioned 13th M305380 custom configuration command, the visible partition can be switched to reach the substantially accessible user. The power of multiple partitions of area 511. In addition, with the first embodiment, the problem of backward compatibility of the aforementioned conventional techniques between different specification versions can also be avoided. Taking an SD ν2·0 high-capacity card with a user area of more than 2 GB as an example, the user area can be divided into multiple zones (which can be pre-divided or re-divided by using the aforementioned fourth custom configuration command). The capacity of one partition is not more than 2GB, and the communication protocol supported by each partition is adjusted to the previous version (the version can be preset or adjusted by using the aforementioned fifth custom configuration command), so that only the external device of the previous SD version is supported. Accessible visible partitions (ie, custom external devices) or all partitions (ie, the first custom configuration command can be issued). In an embodiment, in the first to fifth custom configuration commands, each of the custom configuration commands may be one of the following: (1) The custom configuration command is a manufacturer reserved command (Manufacture Reserved Command). Manufacturer-reserved orders are commands that each support communication agreement retains for the manufacturer's flexible use, and the manufacturer can use it to design orders that meet their needs. The manufacturer's reserved command contains command index fields and command parameter blocks. The value of the command index is selected from the values allowed by the support agreement, and the command parameters contain information about the system area to be updated by each custom configuration command. For example, the command parameters of the first custom configuration command include specifying which partition to switch to. (2) Custom configuration commands (4) The general write command specified in the support rail agreement, and specify a bit 14 M305380 that does not belong to the address range of the visible partition. For example, if the address range of the visible partition is, the designated address may be an address of not less than 128M. As for the information of the system area 512 to be updated by the custom configuration command, it is the same as the general write command to arrange the data to be written, for example, directly after the general write command. (3) The custom configuration command is a general write command specified by the support protocol, and specifies a least bit (leastsigniflcantbit, LSB) address that is not zero. In some support protocols, such as SD and MMC's data transmission units are larger than one byte, and each logical address represents a tuple-sized memory space. Therefore, it is stored in the visible partition. In the general read and write command, the specified address is a value divisible by 2, so the lowest bit of the specified address is zero. In this aspect, the above-described characteristics are utilized, and the general write command is also used, but the address where the lowest bit is not zero is additionally specified to represent the access to the system area 512. The information of the system area 512 to be updated by the custom configuration command is the same as that of the general write command arrangement. In another embodiment, the first custom configuration command may be one of the following: (A) a custom configuration command is a general master command specified by the support protocol, and one is specified. An address that exceeds the addressing range of the visible partition. For example, if the address range of the visible partition is 〇~(128M_1;), 15 M305380, the specified address may be an address of not less than 128M. (B) The first custom configuration command is the general 'fetch command' specified by the support protocol and specifies an address where the lowest bit is not zero. The reason is similar to (3) above. In the foregoing two aspects (A) and (B), after receiving the first custom, and sorrow command, the controller 53 partitions the visible partition k according to a preset switching sequence. Switch to the next partition. For example, the preset switching sequence can be set as partition 5111 - partition 5112 - third partition 5113 - first partition 5111 〇 < 苐 2 embodiment> Figure 6 is a second implementation of the memory device with multiple partitions of the present creation Example block diagram. The magnetic device 60 supports a standard communication protocol and includes a = volatile memory 61, a transmission interface 62, and a control 63, as shown in FIG. The standard communication protocol includes one of the following: Cong, cf, MS, MMC, and SD. In one embodiment, the memory device 6 is a portable device. The non-Zenary hybrid 61 N includes a user area 611 that includes a -custom partition 6112 and a non-custom partition 6111. To access the custom partition 6112, the first-authentication-authentication action (below) is not required. In an embodiment, the non-volatile memory (four) is a flash memory or a hard disk. The interface of the transmission interface 62—the external device 64 receives the authentication message, the authentication information has a guest cell that is not standardized in the fresh communication protocol. The M305380 controller 63 is switched to the transmission interface 62 and the non-volatile memory 61. According to the authentication information, it is determined whether to allow the external device to access the custom partition 6m. The custom format of the pre-certification information, which is not regulated in the standard communication protocol, means that the format can be customized by the manufacturer, for example, as many bits as possible, as long as it is compatible with the standard protocol. If the authentication information includes a custom identification code, the controller 63 allows the external skirt 64 to access the custom partition 6112. If the authentication information does not include the guest φ t identification code, the control 11 63 does not allow the external device 64 to access the custom partition 6112. In other words, in the user area 611, the access of the custom partition 61丨2 is authenticated, so that the data protection function can be provided. Instead of the custom partition 6111, the standard read-and-write command access is standardized. #八f In a real example, the custom partition 6112 is further subdivided into a read-only sub-partition, a single overwrite sub-partition and a multiple overwrite sub-partition (5) not shown =) ' to provide different storage aspects . In the case where the custom partition 6112 itself has a multi-overwrite function (such as using flash memory), by the controller 63, in conjunction with the external device 64, the equivalent read-only or early can still be achieved. The function of overwriting. In the case of a read-only sub-partition, the information contained therein is: when it is written, it can be stored by using the tool to store a special guarantee, such as the product registration number of the memory device. The external device ^ can store the history data used by the application in the single-overwrite sub-partition, and the date used by the female f-person. For the application T which requires network startup (Activati〇n), the calculation of the dynamic grace period - 〇d) by overwriting the sub-partition. Repeat overwrite sub-sections within ^

The user area 711 includes a plurality of partitions (the number of partitions is not limited, and FIG. 7 is based on two partitions 7111 and 7112), wherein the partition 7111 is set as a preset partition (the meaning of the preset partition is described later) . The system area 712 stores the location information for each partition for use by the controller 73 to address the partitions. In the - _ towel, per-partition location information, partition capacity. According to the partition capacity, the button is performed, that is, the partition valley 1 has the effect of displaying the partition location (which will be exemplified later). In another embodiment, in addition to the partition capacity, the location of each partition also includes a sub-start address. The face 72 can receive an access command issued by the external device 74 that is compatible with the standard communication age and sent to the control (four) 73.

The partition to be accessed. In other words, the address of the access command at this time contains all the partitions of the user area 711. For example, if the location of each partition contains the partition capacity, Lai _, the capacity of partitions 7111 and 7U2 are face B, 256MB, respectively, and assuming that each logical address represents the memory space of the size of the byte, then the custom The external device can use the address of 〇~(128M-1) to address the partition 7111, and utilize the address of the mosquito site 1111 of the 1st ~ (12 256 Μ · 1). For example, if the location information of each partition includes the partition capacity and the partition start address, still take FIG. 7 as an example. The capacities of the partitions 7111 and 7112 are 128_ and 256 MB, respectively, and the partition start addresses are A1 and Α2, respectively. The custom external device can use the address of Α1~(Α1+128Μ-1) to address the partition 7111, and use the address of Α2~(Α2+256Μ-1) to address the partition 7112, wherein the setting of the sub-address "α2" is required. The two addressing ranges of ΑΗΑ1+:;;^ Α2~(Α2+256Μ-1) do not overlap. The controller receives the access command issued by the custom external device, that is, according to the logic specified by the access command. Address and location information of each partition, converting the specified logical address to a physical address for accessing the partition 7111 or partition 7112. It is worth noting that the general read and write commands specified by the standard communication protocol are used, and The system area 712 cannot be accessed. However, if the external device 74 can issue a custom designed M305380 sad command that is compatible with the standard communication protocol (the aspect of which is detailed later), the system area can be updated. Information stored In the example, the controller 73 updates the location information of the partition according to the sixth configuration command issued by the external device % to adjust the number of multiple partitions of the user area 711. For example, when the location is in the partition capacity, the controller 73 The capacity of the partition is set to zero to shift = the capacity record is added or added as the capacity of the new partition. In another embodiment, when the location information stores the partition capacity, the controller 73 is issued according to the external device 74. The seventh configuration command updates the location information to adjust the capacity of any of the user areas 711. In still another embodiment, the controller 73 is based on the external device 74 when the location information stores the partition start address. The eighth configuration command is issued, and the location information is updated to adjust the start address of any partition of the user area 711. In an embodiment, in the foregoing sixth to eighth custom configuration commands, The parent-custom configuration command can be one of the following: (1) The custom configuration command reserves a command for a manufacturer. The manufacturer retains the command that the standard communication protocol retains for the manufacturer to flexibly apply the command. The command index block and the command parameter block are included, the value of the command index is selected from the value allowed by the standard communication protocol, and the command parameter includes information to be updated by the system configuration area 712 by each custom configuration command. For example, The command parameters of the seven-custom configuration command include which partition is specified for adjustment and the adjusted capacity value. () The guest group evil command is the general write command specified by the standard communication protocol' and specifies that one does not belong to the user. The address of the address range of the region 711 is 21 M305380. For example, if the address range of the user area is 0 to (512 M_1), the designated address may be an address of not less than 512 M. As for the custom configuration command to be updated The resources of the system area 712 are the same as the way the general write command schedules the data to be written, for example, directly after the general write command. (3) The custom configuration and command are the general write commands of the fresh communication mosquito, and specify an address where the least significant bit (LSB) is not zero. As described in the previous embodiment, in some standard communication protocols, a general write command is used, but an address specifying that the lowest bit is not zero may be used to represent the system area 712 instead of the user area 71. The information of the system area 712 to be updated by the custom configuration command is the same as the way the general write command arranges the data to be written. With the third embodiment of Figure 7, it is possible to avoid the compatibility problem of the surface technology when accessing multiple partitions by different external devices.
