ABSTRACT:
Internal voltage generators are provided, as well as methods of overdriving an internal voltage generation circuit. Embodiments of the internal voltage generator comprise a first driver for receiving an external voltage to supply an internal voltage to the internal circuit in response to an input voltage; a comparator for comparing a reference voltage with a fed-back internal voltage to generate the input voltage of the first driver; a variable pulse generating circuit responsive to an input pulse; and a second driver for dropping the input voltage of the first driver to a ground voltage in response to the variable pulse produced by the variable pulse generating circuit. The internal voltage generator can generate the internal voltage of a relatively constant level without regard to increase of the external voltage or frequency of an operating signal.
