Fast access system for solid state storage devices

The present invention relates to a fast access system for solid state storage devices, and more particularly to a fast access system for a solid state storage device.

SD (secure digital) memory card, referred to as SD card, is often used in portable electronic products such as digital cameras and mobile phones to store photos, videos or music. SD cards generally contain a controller, and the supported transmission modes include SPI (serial peripheral interface) mode, 1-bit transmission mode, and 4-bit transmission mode.

Please refer to FIG. 1 , which illustrates a conventional SD card read/write architecture. As shown in FIG. 1, a USB card reader 10 is coupled to a USB interface 21 of a personal computer 20 to provide an access function for the SD card 30.

However, this SD card read/write architecture cannot meet the batch planning requirements of a large number of SD cards, and its operation requires installing a driver in the personal computer 20 to drive the USB card reader 10 to access the SD card 30.

In order to solve the batch planning problem of the SD card, it is known that an SD card reading and writing device capable of batch planning an SD card is proposed. Please refer to FIG. 2, which is a block diagram of a conventional SD card reading and writing device. As shown in FIG. 2, the SD card reading and writing device has a plurality of processing units 40, a plurality of SD card controllers 50, and a plurality of SD card slots 60 for batch planning a plurality of SD cards 30.

However, since the SD card reading and writing device accesses the memory space of each SD card 30, communication and command/data transmission between the processing unit 40 and the SD card controller 50, and the SD card controller are required. Communication between 50 and SD card and command/data transmission, so the batch planning still takes a long time to complete.

In order to solve the aforementioned problems, we need a novel solid state storage device access system.
