A method for controlling an internal supply voltage generating circuit reduces power consumption in an active mode. The internal supply voltage generating circuit includes a first voltage-drop regulator, which supplies a relatively large driving power to an internal circuit, and a second voltage-drop regulator, which supplies a relatively small driving power to the internal circuit. First, the second voltage-drop regulator is activated and the first voltage-drop regulator is inactivated in one of a stand-by mode and a power-down mode. Then, at least the first voltage-drop regulator is activated in an active mode, and the first voltage-drop regulator is inactivated in an active pause of the active mode. The first voltage-drop regulator is activated when the active pause is cancelled.
