Abstract: A charge pump circuit utilizing accumulation capacitors for use in EEPROM devices so as to internally pump up an external power source voltage includes a plurality of MOS transistors (T101, T102; T201, T202) and accumulation capacitors (N2, P2). The plurality of MOS transistors are connected in series between a first input voltage terminal and a higher voltage output terminal. The first input voltage terminal receives the external power source voltage. The accumulation capacitor has a first plate and a second plate. Each of the first plates of the accumulation capacitors is connected between adjacent ones of the plurality of MOS transistors. Each of the second plates of the accumulation capacitors is connected to a second input terminal for receiving a clock signal. As a result, the pump circuit can be operated effectively so as to produce a significant reduction in power consumption.
