ABSTRACT:
The present invention provides an internal voltage generator for maintaining a voltage level of an internal voltage by forcibly discharging an over-supplied voltage. The internal voltage generator includes a reference voltage generator for outputting at least one reference voltage with a predetermined voltage level after receiving an external voltage; a level shifter for outputting an internal reference voltage with a shifted voltage level by receiving the reference voltage of the reference voltage generator; a driver for outputting an internal voltage by using the internal reference voltage; and a discharging unit for forcibly discharging an over-supplied voltage of the internal voltage by a release pulse signal.
