Abstract
A delay due to retry processing with regard to occurrence of a memory write error is suppressed. A sub-region command holding section holds a host command as a sub-region command divided with respect to each access target sub-region. A sub-region address conversion section converts an address of an access target sub-region to an address of a memory regarding a sub-region command. A sub-region command execution section executes a sub-region command whose address has been converted, and accesses a memory. In a case where a write error occurs in a memory regarding a sub-region command, an address conversion management section performs preparation processing of a substitute region for a sub-region command in which the write error has occurred concurrently with execution of another sub-region command in the sub-region command execution section.
