Abstract:
A semiconductor memory device is provided. The semiconductor memory device can suppress increases in power consumption. As a result, damage to the data normally caused by row problems can be prevented. The semiconductor memory device includes a control unit. The control unit controls the time interval for refreshing the memory. If the frequency of a read/write access requirement to the memory during a predetermined period is higher, then the control unit shortens the interval between memory refresh operations.
