High voltage generator
A high voltage generator includes a charge pump configured to output a pumping voltage in accordance with a first clock signal and a second clock signal having a level opposed to a level of the first clock signal; a first regulator configured to stabilize the pumping voltage to a voltage having constant level, thereby outputting a first regulation voltage; and a second regulator configured to convert the first regulation voltage into a voltage having constant level, thereby outputting a second regulation voltage. Here, the first regulator increases the pumping voltage by n number so that the first regulation voltage reaches a first level, and the second regulator increases the first regulation voltage by m number so the second regulation voltage reaches a second level smaller than the first level.
