[Technical field to which the invention belongs] ', the invention depends on the type: #material access method (10) system, especially a memory card data access method and training, and its application Microcontroller chip and card machine. [Prior Art] Portable digital electronic devices (C〇nventi〇nai handheld • C〇mpUtingdevice) are constantly being updated, and jointly used to expand the flash of the electricity in the government's storage valley. (Hash memory card) industry. (4) Silk development. In the market, there are two different memory card specifications in the township to promote the use of different electronic devices. Memory cards used in digital cameras, such as digital cameras and digital video recorders, digital music players and personal digital assistants, must be connected to the computer through a card reader (Card reade) to access the data stored in the memory card. The use of computer software to present and edit data. The current development of card readers focuses on the integration of multiple specifications memory card development in a single machine, so that consumers can use the same card reader to access different types of memory cards. The size, signal pin and data transmission mode of the memory card are one of the main design topics for the internal microcontroller chip of the card reader and card reader. For example, Taiwan Patent Application No. 092133447 proposes fast access. The flash memory card method and device are used to access data of multiple memory cards of different specifications. • Under the influence of the miniaturization trend of digital electronic devices, mainstream memory cards (SD/MMC/MS) are successively launched. The new and miniaturized specifications, for example, the SD digital card series include the standard 5 1331305 card, Mini SD card and Micro SD. In addition, the data transmission mode has also evolved. For example, the SD series specification memory card includes: two data transmission modes: position and 4-bit, and the MMC series specification memory card includes 1 bit. Three data transmission modes: yuan, 4-bit and 8-bit. The data access function of the card reader is mainly for the data transmission mode of the latest version of the current memory card. 'For the purpose of accessing the old memory card. The design of the card machine is compatible. Therefore, the new version of the memory card has the data transfer mode of the old memory card to match the access of the card reader.

Please refer to the fifth A bus block 300 thumb ^ C map" These figures are the fourth diagram of the programmable, dry example diagram. In this example, The program bus 12 ===:=, is pre-determined as the data channel bit and the first transmission channel 301, the brother-, the channel 3〇2 and the third-pass channel of the 1-bit. Display single-Μμ〇 memory card i9i Because this specification can use 丨& mode to transmit h-gate 7", 4-bit and 8-bit data transmission ^Transfer Bellow', therefore, for single memory card i9i, channel switching Cry == control the first transmission channel 3〇1 and the second transmission channel 3〇2 :; : The data of the transmission (9) is used as a link to simultaneously use the second transmission channel of the first transmission material to transmit the full-speed 8-bit data. The 刖杈 type accesses the memory card 丨 91. The fifth B shows the continuation of the two MMC memory cards 191, 192. When accessing the two memory cards 191, 192, the channel switcher mode : The 380 system controls the first transmission channel 3 and the data path of the second transmission channel is respectively connected with the data of the memory card 19H92, so as to The data is accessed by the memory card 19 192 by using the pen-passing wheel channel 301 and the second transmission channel 〇2. The example is applicable to the memorizing cards 191 and 192 respectively for the MMC memory card. With SD memory card, the time is the case of SD memory card. σ The fifth c-picture shows three mmc memory cards 19 192 read situation. When three memory cards 19 192, 193 are stored overnight switch The module 380 controls the data paths of the first transmission channel 3〇1, the channel 302 and the third transmission channel 303 to be respectively connected to the data of the second (9), the defeat, and the (9), so as to utilize the first transmission 301, the second The data transmission mode of the transmission channel 3〇2 and the third transmission channel 3〇3, respectively, 2nd, 2nd, 4th, and 0% of the data is transmitted to the memory card (9), off, 13 1331305 ^93. This example is applicable. On the memory card 191, 192, 193 = memory purchase use, and the same (four) number of sheets =:: = this _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Width' thus uses the best data for poor material access, which is a flexible and efficient data access, 'above, The detailed description and drawings of the specific embodiments of the present invention are not intended to limit the present invention, and all the scopes of the present invention are subject to the scope of patents. Anyone familiar with the art is in this i =: special = thinking The changes can be covered in the following [simplified description of the drawings].
