ABSTRACT:
An internal voltage generator according to the present invention stably supplies an internal voltage regardless a level of power voltage input from a source external to a semiconductor memory device. The present invention includes a dead zone controller to generate a reference voltage, a high reference voltage and a low reference voltage based on an inputted power voltage; and an internal power generator to generate an internal power based on the reference voltage by comparing the internal power with the high reference voltage and the low reference voltage.
