Abstract
In one embodiment, a semiconductor device includes a reference voltage supply circuit configured to supply a first reference voltage and a second reference voltage. The device further includes a power source voltage supply circuit including a first power source voltage generator supplied with the first reference voltage and configured to generate a first power source voltage, and a second power source voltage generator supplied with the second reference voltage and configured to generate a second power source voltage, the power source voltage supply circuit being configured to supply the first power source voltage and the second power source voltage to a power source voltage line. The device further includes a voltage control circuit connected to the power source voltage line, and configured to control a value of the first reference voltage and a value the second reference voltage.
