    摘要： A semiconductor integrated circuit includes a plurality of units. Each of the units includes a power supply pad, a function circuit, and a power supply control circuit. The plurality of units each have a first state in which the function circuit is in an operating state by the power supply pad being at a prescribed operating potential and a second state in which the function circuit is in a non-operating state by the power supply pad being at a prescribed non-operating potential. The power supply control circuit includes a switching circuit for connecting the power supply pad to the prescribed non-operating potential. The power supply control circuit in each of the plurality of units closes the switching circuit when at least one of the other units is in the first state and opens the switching circuit otherwise.
