ABSTRACT:
A semiconductor device including a pumping capacitor for inducing a high voltage, a switching circuit for transferring the high voltage induced by the pumping capacitor and a switching control circuit for controlling the switching circuit, wherein the switching control circuit includes a first capacitor for inducing a switching control voltage to a first node in response to an oscillation signal, a first switching MOS transistor for transferring the switching control voltage applied to the first node to a second node, and a first turn-on controller for maintaining the first switching MOS transistor to be turned on, and allowing a voltage below a predetermined voltage difference to be applied between the first node and a gate of the first switching MOS transistor.
