ABSTRACT:
A controller102and four flash memories F0to F3are connected by twos to two memory buses, and each flash memory is divided into two regions of substantially the same size to form a first half and a last half regions. In a four-memory configuration, a consecutive logical address specified by a host apparatus is divided into a predetermined size, and a write operation is performed in a format that repeatedly circulates through F0, F1, F2, F3in this order. In a two-memory configuration, the write operation is performed in a format that repeatedly circulates through F00, F10, F01, F11. Thus, a controller processing is made common regardless of the number of flash memories connected to the controller.
