Semiconductor disk storage apparatus including a plurality of flash memories and a buffer memory to continuously write data responsive to first and second write commands

摘要

A semiconductor disk storage apparatus is coupled with a system bus for receiving a write request accompanied with first and second blocks of data through the system bus. A plurality of nonvolatile flash semiconductor memories store the first and second blocks of data therein. A buffer memory holds the first and second blocks of data as write data to be written into the flash memories. A control means carries out read operations of the write data from the buffer memory and write operations of the write data read out from the buffer memory into the flash memories, responsive to the write request. The control means responsive to the write request, sends a first write command to write the first block of data into one of the flash memories and a second write command to write the second block of data into a different flash memory.
