Description

  The present invention relates to a card reader, and more particularly, to a card reader that can be inserted into an application system to improve application system efficiency.

  The use of personal computers is already widespread and has become a usage tool that people have to rely on every day, whether for work, entertainment or learning. With the rapid development of science and technology, technologies in various fields, such as hardware devices, application software, and work systems, have been improved and updated in accordance with their development in the related areas of personal computers.

  For users, replacement frequency of personal computer hardware devices is usually less frequent than application software updates. That is, a set of hardware devices can generally meet the needs of most application software, but considering the current work system promotion, the work system functions will become increasingly larger, so there is more software that is consistent. In this case, the hardware resources occupied by the work system itself increase accordingly. At this time, if the user tries to replace a newer work system, the user must consider updating the hardware device of the personal computer at the same time in order to improve the efficiency and make the operation appropriate. Otherwise, not only the work system itself cannot operate smoothly, but also the application software installed in the work system cannot obtain a suitable use situation.

  The most important way to improve the efficiency of personal computer hardware is to start by increasing the system memory (DRAM). However, the method of improving efficiency by purchasing additional system memory not only increases the cost of user consumption, but also determines whether the main board you are using can be supported, or the total number that can be supported. You have to think about it, sometimes you can't expand it by replacing the old system memory, and even you have to replace the main board that you originally used. For this, the cost increases and becomes wasteful.

  On the other hand, memory cards are increasingly used, and card readers are gradually becoming widely used by people. Advantages well known to people of conventional card readers are that they are convenient to carry, support various memory cards, and easily transfer data to and from a personal computer. Card readers are now the most convenient transfer medium between memory cards and personal computers. Therefore, when a user additionally purchases a card reader for his / her personal computer, it has the effect of improving the application system efficiency together with the application function of the card reader, and the efficiency can be improved only at a lower cost. Is desirable.

  In view of the above, the technical problem to be solved by the present invention is that the flash memory design is built in the card reader, and in the application system, the flash memory is used as the system memory in accordance with the program that matches the memory function. And achieving the purpose of expanding the memory and improving the efficiency of the application system. According to the concept of the present invention, the user can not only have the application function of a card reader, but also can increase the memory for the application system that he / she is using to reliably improve the application system efficiency. become able to.

  In order to achieve the above-mentioned object, one plan according to the present invention is inserted in a case of an application system having an external memory drive, and includes an at least one memory card connector, a flash memory and a control unit. A card reader capable of improving efficiency is provided. Among them, the memory card connector is for inserting a compatible standard memory card, and the flash memory is a memory for driving and matching when an external memory drive is operated. The control unit is electrically connected to the memory card connector and the flash memory, and is connected to the application system. The memory card and the flash memory can exchange data with the application system by the control unit. Therefore, the flash memory becomes an extended memory of the application system due to the alignment of the external memory drive, the memory space of the entire application system is increased, and the object of improving the application system efficiency is achieved.

  Hereinafter, a detailed description of the present invention will be given with reference to the accompanying drawings. As a result, the features and technical contents of the present invention can be understood more deeply, but those accompanying drawings are used only for reference and explanation, and needless to say, the scope of the present invention is not narrowly limited. is there.

  FIG. 1 is a schematic diagram illustrating a card reader that can improve the efficiency of an application system according to the present invention. As shown in the figure, the present invention provides a card reader 10 that is inserted into an application system 1. Although the application system 1 of the present embodiment will be described using a desktop personal computer as an example, the application system 1 may be, for example, a notebook personal computer or an apparatus of another work system.

  The card reader 10 according to the present invention includes at least one memory card connector 101, a flash memory 102, a control unit 103, and an interface connection port 104. The memory card connector 101 is used by a user to insert a memory card 2 of a compatible standard. For example, in this embodiment, four memory card connectors 101 are provided, and each memory card 2 is different (for example, a CF card: Compact Flash). Card etc.) is inserted. The memory card 2 used by the user can access data with the application system 1 by the card reader 10. As shown in the figure, the actual mode of the memory card connector 101 may be a single transfer standard memory card connector, but, for example, a large number of memory card connectors in which a plurality of transfer standards are designed. It may be.

  A flash memory 102 (for example, a NAND flash memory) according to the present invention is mainly used as an extended memory of the application system 1 except that the user provides data access, and is connected to the application system 1 from the outside. By matching the flash memory 102 with the extended memory used for the system itself, the memory space of the entire system can be increased and the processing efficiency of the application system 1 can be improved. The control unit 103 is connected to the application system 1, and the application system 1 can perform data transfer and conversion with the memory card 2 and / or the flash memory 102 by the arithmetic processing of the card reader 10.

  On the other hand, the interface connection port 104 is connected to the application system 1 through, for example, a signal connection line (not shown) to achieve the data transfer operation. Since the card reader 10 according to the present invention is an insert-type card reader 10, the flash memory 102 is used as an extension memory of a predetermined application system 1. However, since the application system 1 does not have to transfer internal data to a predetermined storage device (for example, a hard disk) of the application system 1 before moving the device, the application system 1 reduces the execution program for system occupation. it can.

  In order to explain the technical features of the present invention in more detail, referring to FIGS. 2 and 3 at the same time, FIGS. 2 and 3 are block diagrams and a part of an embodiment of a card reader capable of improving the application system efficiency according to the present invention. It is a reference circuit diagram. As shown in the figure, the application system 1 into which the card reader 10 according to the present invention is inserted has an external memory drive 111, and when the application system 1 is activated, the external memory drive 111 is executed to The flash memory 102 is driven and matched, so that the flash memory 102 becomes an extended memory of the application system 1 and is used for accessing the application system 1 together with the original system memory (DRAM). That is, since the entire usable memory space in the application system 1 is increased, the application system 1 can achieve the object of improving efficiency by inserting the card reader 10 according to the present invention.

  Regarding the structure of the card reader 10, the memory card connector 101 is for a user to insert the memory card 2, and the control unit 103 is electrically connected to the memory card connector 101 and the flash memory 102, Connected to the application system 1, the memory card 2 and the flash memory 102 exchange data with the application system 1 via the control unit 103. Further, the interface connection port 104 is electrically connected to the control unit 103 and is inserted corresponding to the system connection port 12 of the application system 1 to transfer data to be converted between the control unit 103 and the application system 1. To do. In actual application, the interface connection port 104 and the system connection port 12 inserted correspondingly are, for example, USB or SATA transfer interfaces.

  The card reader 10 is further electrically connected to the interface connection port 104, receives the system voltage (for example, 5V) transferred from the interface connection port 104, converts it, and outputs the output voltage (for example, 3.. 3V) and a voltage conversion unit 105 that supplies the control unit 103, the memory card 2, and the flash memory 102, respectively. In the present embodiment, for ease of explanation, the voltage conversion unit 105 is designed to be provided outside the control unit 103. However, when actually applied, the voltage conversion unit 105 is built in the control unit 103. You may design so that cost may be reduced.

  In addition, the application system 1 includes an external memory drive 111, and further includes a buffer memory control module 112 that controls the entire memory space matched by the external memory drive 111 in the application system 1, whereby the application system 1 All the memory spaces can be used, and sufficient files are formed to automatically download files frequently used by the user in advance, thereby improving the reaction time of the application system 1. The buffer memory control module 112 and the external memory drive 111 are stored in, for example, the storage device 11 of the application system 1, and the flash memory 102 in the card reader 10 is stored by connecting the system connection port 12 and the interface connection port 104. Achieve the purpose of alignment and control. Further, the external memory drive 111 and the buffer memory control module 112 are built in the work system of the application system 1 (for example, the functions of Ready Boost and Ready-Drive built in the Microsoft Vista work system) at the time of actual design. Alternatively, a different method such as circumscribing the software program of the work system may be used.

  When the card reader 10 according to the present invention is actually applied to the application system 1, the control units 103 in the card reader 10 are provided in different logic unit numbers for the flash memory 102 and the memory card connector 101, respectively. Therefore, the flash memory 102 and the memory card connector 101 become independent logic units. Therefore, the disk slots displayed corresponding to the card reader 10 in the application system 1 are independent disks. For example, when the card reader 10 has four memory card connectors 101, one flash memory 102 is provided. Therefore, the application system 1 is a device showing five removable disk slots. Therefore, the flash memory 102 may be used not only as an extended memory of the application system 1 but also as a storage device for storing general data files by the user.

  As described above, the present invention is a card reader that can improve the efficiency of the application system, and the flash memory added in the card reader is fixedly formed as the extended memory of the application system by the structure inserted into the application system. Thus, when the user purchases a card reader, the efficiency of the application system itself can be improved in addition to the function of accessing the memory card. In this way, the practicality and versatility of the card reader can be greatly increased.

  The above is merely a preferred specific embodiment of the present invention, and does not limit the scope of the utility model registration claim of the present invention. While appropriate changes and modifications can be made within the field, it goes without saying that such implementation should be delivered within the scope of the claimed invention.
