ABSTRACT:
A semiconductor disk storage apparatus is provided which is coupled to a system bus for receiving a write request accompanied with first and second sector data, each of 512 bytes, through the system bus from an external information processing system. A buffer memory is provided to hold the first and second sector data as write data to be written into a plurality of non-volatile flash semiconductor memories. A control means is also provided which is responsive to the write request to send a first write command to write the first sector data into one of the flash memories, and, after the first write command has been sent, to send a second write command to write the second sector data into another of the flash memories, such that the sending of the second sector data accompanied with the second write command occurs while the write operation of the first sector data is still being carried out.
