Then, an inner counter CNT and an X-address system circuit for refreshing are operated, only the refreshing operation is executed and data within memory array ARY is held. When the power source voltage is a normal level, a high-speed property is guaranteed. When it is lowered, the power source voltage is detected even when no control signal is used and a mode is automatically switched to a low power consumption mode. Thus, a semiconductor memory ARY where data is held is obtained.
