ABSTRACT:
An internal voltage generation circuit includes a signal generation unit which generates first and second level signals and first and second control signals from a reference voltage generated by voltage-dividing an internal power and generates first and second driving signals by comparing levels of the internal power and the reference voltage, a driving control unit which receives the first and second level signals and drives the internal voltage in response to an active signal, and a driving unit which receives the first and second driving signals and drives the internal voltage.
