Description of the invention (1) Technical field to which the invention belongs: The present invention relates to a storage device reading and writing device, and more particularly to a storage device reading and writing device without a built-in microprocessor. Prior technology: Traditional memory card reading and writing devices (such as card readers) have a built-in microprocessor control unit (MCU) to process instructions sent from the computer to the memory card. Referring to the first figure, a connection relationship between a conventional memory card reading and writing device 10 and a computer and a memory card 60 is shown. Taking writing data to the memory card 60 as an example, the operation between the conventional memory card reading and writing device 10 and the computer and the memory card 60 is described below. The computer sends S C S I (Small Computer System Interface) commands and data to the universal serial port interface (USB interface) 30 via the south bridge chip 20. The universal serial port interface 30 sends SCSI commands and data into a USB packet and sends it out. The microprocessor 40 then interprets the USB packet into a USB packet. After remembering the card control instructions and data, the memory card control instructions and data are transmitted to the memory card interface 50, and finally the memory card interface 50 stores the data into the memory card 60 according to the memory card control instructions. The microprocessor has basic microinstructions, and the driver of the traditional memory card reader / writer uses the method of calling these microinstructions to handle the communication between the computer and the memory card reader. The main function of the microprocessor is U g b instruction
