Abstract
A charge pump unit structure of a charge pump circuit includes a booster circuit unit, a positive pump transfer unit and a negative pump transfer unit. An output terminal of the booster circuit unit is connected to an input terminal of the positive pump transfer unit through a first switch circuit and to an input terminal of the negative pump transfer unit through a second switch circuit. An erase enable signal is connected to control terminals of the positive and negative pump transfer units. A first enable signal is connected to control terminals of the positive pump transfer unit and the first switch circuit. A second enable signal is connected to control terminals of the negative pump transfer unit and the second switch circuit.
