ABSTRACT:
An internal voltage control apparatus capable of reducing current consumption and a semiconductor memory device using the same includes an enable signal generating unit for generating an enable signal in response to an active signal and an internal voltage driving unit driven by the active signal and the enable signal, wherein the internal voltage driving unit drives an internal voltage by comparing the internal voltage and a reference voltage and then generating first and second driving signals, and wherein the enable signal generating unit receives the second driving signal and then determines enablement of the enable signal.
