    • A semiconductor device includes an internal circuit and first and second supply voltage-lowering circuits in its semiconductor chip. The first supply voltage-lowering circuit steps down an external power supply potential of the semiconductor chip in response to a control signal, generates a first internal power supply potential, and supplies it to the internal circuit. The second supply voltage-lowering circuit steps down the external power supply potential of the semiconductor chip in response to the control signal, generates a second internal power supply potential of substantially the same level as that of the first internal power supply potential, and supplies it to the internal circuit. The first and second internal power supply potentials output from the first and second supply voltage-lowering circuits vary out of phase with each other to cancel out variations in first and second internal power supply potentials.
