ABSTRACT:
A device for controlling a voltage of a semiconductor integrated circuit includes a voltage selecting unit that generates a voltage selecting signal for selecting a voltage to be controlled among a plurality of voltages by using a first control signal, a control step selecting unit that generates a control step selection signal for selecting a control step of the voltage to be controlled by using a second control signal, and a voltage controlling unit that controls a level of the voltage to be controlled among the plurality of voltages in response to the control step selection signal.
