Abstract
A semiconductor device comprises a plurality of circuit blocks, a plurality of local wirings which supply power to the plurality of circuit blocks, respectively, a global wiring which supplies the power to the plurality of local wirings, a plurality of first switches which are disposed between the plurality of local wirings, respectively, and the global wiring, and a second switch which is disposed between two local wirings. A power control unit controls open/close of the plurality of first switches and the second switch based on the potential difference between the two local wirings.
