ABSTRACT:
A voltage pumping device is disclosed. The device comprises a reference voltage generator for generating a reference voltage having different levels depending on whether a semiconductor device is in a self-refresh mode or not, a voltage level detector for outputting a voltage pumping enabling signal in response to the reference voltage and a specific voltage fed back thereto, a voltage pump for performing a voltage pumping operation in response to the voltage pumping enabling signal to output the specific voltage, a discharge controller for outputting a discharge control signal in response to the reference voltage and the specific voltage, and a discharge circuit for discharging an output terminal of the voltage pump to a desired voltage level in response to the discharge control signal.
