ABSTRACT:
A multi stage voltage pumping circuit includes a plurality of voltage pumping stages each operated by a first clock signal and a second clock signal for raising a voltage level of an inputted voltage; and a plurality of charge storing means each connected to outputs of the plurality of voltage pumping stages respectively except for a last voltage pumping stage in order to store charge, wherein each of the plurality of voltage pumping stages is a cross coupled voltage doubler and an output of a previous voltage pumping stage is connected to an input of a next voltage pumping stage.
