STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To make fast the transfer of data between a buffer and a flash memory by inputting and outputting data to and from a memory module at higher speed. SOLUTION: The memory module 4 is constituted by connecting the buffer 3 to flash memories 2 by a bus 9. The memory modules 4 are connected to a controller module 1 by an internal bus 8 to constitute an auxiliary storage device 5. A host system 6 sends a request to access data to the auxiliary storage device 5 through a bus 7. The controller module 1 sends an indication to multiple memory modules 4 at the same time to send and receive data to and from the flash memories 2 in parallel through the buffer 3.
