A high voltage control circuit of a semiconductor device includes an output node control circuit configured to set an initial potential of an output terminal or to discharge the potential of the output terminal, in response to an input signal and a high voltage supply circuit comprising an acceleration unit and a potential control unit coupled in series between the output terminal and a supply terminal for supplying a high voltage. The acceleration unit is operated in response to the potential of the output terminal, and the potential control unit is operated in response to the input signal.
