ABSTRACT:
An internal voltage generator maintains stable level of an internal voltage without increasing physical area. The internal voltage generator includes an active level detector for detecting a level of an internal voltage by comparing the level of the internal voltage and a level of a reference voltage to thereby output a first active driving signal, a first active driver for providing the internal voltage in response to the first active driving signal, a driving time controller for generating a time driving signal activated for a predetermined time, an active driving controller for activating a second active driving signal while the time driving signal is activated and for outputting the first active driving signal as the second active driving signal while the time driving signal is inactivated, and a second active driver for providing the internal voltage in response to the second active driving signal.
