ABSTRACT:
In a semiconductor memory device, a self refresh cycle program circuit is provided and a refresh operation is conducted in accordance with one of the refresh cycles programmed in the refresh-cycle program circuit. The refresh cycle of the self-refresh mode is selected from a plurality of refresh-cycle types. A plurality of refresh modes allows a refresh cycle to be selected from a plurality of refresh-cycle types in accordance with a selected refresh mode.
