Abstract
A semiconductor apparatus may include a logic circuit and a power control circuit. The logic circuit operates by being supplied with power through a power line. The power control circuit includes a plurality of power switches, and supplies a first power supply voltage and a second power supply voltage to the power line. When a mode of the semiconductor apparatus is changed, the power control circuit causes the plurality of power switches to sequentially stop supplying one of the first power supply voltage and the second power supply voltage to the power line, and then causes the plurality of power switches to sequentially supply the other of the first power supply voltage and the second power supply voltage to the power line.
