ABSTRACT:
A high voltage generation circuit includes a pump clock generation unit configured to generate a pump clock signal in response to a pumping enable signal, a charge pump configured to generate a high voltage on an output in response to the pump clock signal, and a switching unit to selectively couple the output of the charge pump to an output node in response to the pumping enable signal.
