ABSTRACT:
The internal voltage generation circuit includes an internal voltage enable signal generation unit generating an internal voltage enable signal whose enable pulse width is controlled according to an external voltage. An internal voltage generation unit generates an internal voltage corresponding to a reference voltage according to the internal voltage enable signal. The internal voltage generation circuit generates an internal voltage according to an internal voltage enable signal whose enable pulse width is controlled in response to an external voltage, and thus current consumption is improved, and the internal voltage generation circuit provides a stable internal voltage.
