摘要
A voltage generation circuit includes a voltage comparing circuit to compare a reference voltage signal Vi and an internal power supply voltage Vcc and a current supply transistor to supply current based on the output voltage of the voltage comparing circuit and maintain Vcc. The voltage generation circuit also includes a reference voltage signal generation circuit which responds to a control signal ACT activated for a prescribed time period prior to the operation timing of a load and sets Vi=Vref when control signal ACT is inactive and Vi=Vref+ &Dgr;V when control signal ACT is active.
