ABSTRACT:
An internal voltage generation circuit includes a level detection unit configured to generate a detection voltage corresponding to a voltage level difference between a reference voltage with an internal voltage, an oscillation signal generation unit configured to generate an oscillation signal having a period corresponding to a voltage level of the detection voltage, and an internal voltage generation unit configured to generate the internal voltage in response to the oscillation signal.
