Abstract
Disclosed is an internal voltage generator, which includes a detecting means for detecting a level of an internal voltage, an oscillator for generating a driving pulse signal in response to an output signal of the detecting means, a first driving unit for outputting a first pulse signal after receiving the driving pulse signal, a second driving unit for outputting a second pulse signal after receiving the driving pulse signal, and a pumping unit for changing a potential level of the internal voltage after selectively receiving one of the first pulse signal and the second pulse signal.
