ABSTRACT:
A semiconductor memory executes an access operation on one of a plurality of memory blocks in response to an externally supplied access request. At this time, in response to the access request, a memory control unit executes the access operation on one of the memory blocks and a refresh operation on at least one of the memory blocks on which the access operation is not executed. Consequently, it is possible to execute the refresh operation during the execution of the access operation without any conflict between the access operation and the refresh operation. As a result, the access cycle time can be shortened, which can improve the data transfer rate.
