ABSTRACT:
A level determining circuit performs level determination of a potential of a boosted potential node. A determination control circuit is provided for controlling a level determination timing of the level determining circuit. The determination control circuit supplies a control pulse signal of a long cycle to the level determining circuit when a charge pump is not operating, and supplies the control pulse signal of a short cycle to the level determining circuit when the charge pump is operating. The level determining circuit performs the level determination in accordance with a timing defined by the control pulse signal supplied from the determination control circuit. In response to the result of determination, the charge pump is driven. In this manner, a power consumption of a semiconductor memory device can be reduced, and overshoot of a boosted potential of the semiconductor memory device can be prevented.
