The memory controller is provided with a refresh clock generation unit, a control signal generation unit, and a refresh request generation unit. The refresh clock generation unit generates a clock obtained by frequency dividing a system clock, as a refresh clock. The control signal generation unit issues a refresh command to a memory, based on the refresh clock. The refresh request generation unit curtails, based on a specified refresh count in a specified refresh period determined by the memory, a supply to the control signal generation unit of a redundant refresh clock generated exceeding the specified refresh count, the refresh clock being generated within the specified refresh period. |
