ABSTRACT:
Each of a plurality of pump stages has an input node and an output node and performs a charge pump operation in response to any one of the first and second clock signals. The plurality of pump stages include a first pump stage, in which a charge transfer transistor is connected between the input node and the output node. One end of a pump capacitor is connected to the output node, and the other end is supplied with one of the first and second clock signals corresponding to the first pump stage. A connection switcher connects to the gate of the charge transfer transistor any one of the output node of a pump stage which is supplied with one of the clock signals corresponding to the first pump stage and the input node of a pump stage which is supplied with the other clock signal not corresponding to the first pump stage and which is included in a pump stage row not including the first pump stage.
