ABSTRACT:
A timer circuit which is used for write and erase time control of a semicondcutor memory, and configured so as to transfer a charge of a charge storage capacitor to a charge pump capacitor through a first transfer gate thereafter to repeatedly effect a discharge operation by using a second transfer gate thereby to gradually reduce a charge of the charge storage capacitor, thus performing a timer operation, characterized in that there is provided a circuit for making an adjustment such that a voltage applied to the charge pump capacitor is smaller than a voltage applied to the charge storage capacitor.
