ABSTRACT:
A negative voltage drive circuit according to the present invention comprises a switching means coupled between an input terminal and an output terminal; a cross latch pumping means for controlling the switching means in response to first and second clock signals and for maintaining the lower output voltage than that of said charge pump; and a capacitor which starts pumping operation according to the first clock signal when the output terminal is isolated to the input terminal.
