ABSTRACT:
A high voltage generator includes a high voltage level detector for comparing a boosted high voltage with a reference voltage and generating an oscillator control signal being a first logic level in response to a comparison result; a clock feedback block for receiving the oscillator control signal and an inverse pumping control signal and keeping an oscillator enable signal in the first logic level for a predetermined period; an oscillator for generating a pumping control signal in response to the oscillator enable signal and outputting the inverse pumping control signal to the clock feedback block, wherein the pumping control signal is periodically toggled; and a charge pumping block for generating the boosted high voltage in response to the pumping control signal.
