A high voltage generator includes a charge pump generating a high voltage in response to a pumping clock signal, a charge/discharge circuit responsive to the pumping clock signal and charging the high voltage to generate an output voltage, a comparator for comparing the output voltage with a reference voltage to generate a comparison result, and a clock modification circuit adjusting a pumping slope of the charge pump in relation to the comparison result, wherein the clock modification circuit reduces the pumping slope when the high voltage reaches a target voltage level.
