摘要： A power control circuit is connected between a power supply voltage and a logic circuit to switch power supplied to the logic circuit. The power control circuit includes a plurality of first power gating cells (PGCs) receiving an external mode change signal in parallel, at least one second PGC connected with one first PGC, at least one third PGC connected with the at least one second PGC, and at least one fourth PGC connected with the at least one third PGC. The second power gating cell, the third PGC, and/or the fourth PGC may include a plurality of gating cells. At least one of the second, third, and fourth pluralities has power gating cells connected in series. Each of the first through fourth PGCs switches power supplied in response to the mode change signal.
