ABSTRACT:
An internal voltage generator includes a high efficient charge pump. The internal voltage generator includes an oscillation signal generator for receiving a reference voltage and a pumping voltage to thereby output an oscillation signal, a pump control logic for outputting a pumping control signal and a precharge signal in response to the oscillation signal, and a charge pump for precharging the pair of bootstrapping node by connecting the pair of bootstrapping node in response to the precharge signal to thereby generate the pumping voltage of a predetermined level after precharging the pair of bootstrapping node into a level of the power supply voltage and charge sharing the pair of bootstrapping node and the pumping voltage in response to the precharge signal. Herein, the pumping control signal controls a pumping operation and the precharge signal precharges a pair of bootstrapping node for generating the pumping voltage by pumping a power supply voltage.
