Circuit for generating a substrate voltage and a pumping voltage equipped with a single oscillator

摘要

A DC voltage generator has a substrate voltage pumping circuit (120), a voltage pumping circuit (150), and a single oscillator (100) for generating the pulses to which the substrate voltage pumping circuit and the voltage pumping circuit are jointly sensitive, in such a way that the current consumption of the semiconductor memory device are reduced during the standby states. <IMAGE>
