ABSTRACT:
Provided is an internal voltage generator for preventing an occurrence of leakage current while a charge pumping is not performed. The internal voltage generator includes: a charge pumping unit for pumping an external voltage to generate a high voltage higher than the external voltage; a level detecting unit for detecting a level drop of the high voltage with respect to a reference voltage and outputting a detection signal; an oscillating unit for generating an oscillation signal in response to the detection signal; a pumping control signal generating unit for controlling a driving of the charge pumping unit in response to the oscillation signal; and a charge pump controlling unit for precharging the charge pumping unit in response to the detection signal.
