Abstract
A semiconductor storage apparatus including a controller which writes data into different nonvolatile semiconductor memories in a parallel or timed overlapped manner. The controller, responsive to a write request, sends a first write command to write a 512 byte sector of data to a first nonvolatile semiconductor memory. After the first write command has been sent, the controller sends a second write command to write another 512 byte sector to a second nonvolatile semiconductor memory. Accordingly, the operation of data writing of one sector data, responsive to the first write command, and the operation of data writing of the other sector data, responsive to the second write command, to different ones of the nonvolatile semiconductor memories are carried out in a parallel, or overlapped in time, manner.
