ABSTRACT:
The semiconductor integrated circuit device includes a plurality of decoupling cells that suppress power noise respectively, a plurality of power switches that connect the decoupling cells to a power line respectively, and a control circuit that controls the number of power switches selected from among the plurality of power switches and to be turned on according to power noise to be changed according to the operation state of each of internal circuits driven by a power supplied from the power line.
