Abstract
An improved DRAM includes an internal circuit to be initialized upon start of supply of a supply voltage. The DRAM includes a dummy clock signal generator, and applies a dummy clock signal to a clock signal generator through a switching circuit until a predetermined time period elapses after the start of supply of the supply voltage by a timer circuit. A signal /RAS is controlled in a special manner, is not required for initializing an internal circuit such as a refresh counter. Therefore, a load required in the external circuit for initialing the DRAM is reduced.
