Semiconductor device
A semiconductor device with short overhead time. The semiconductor device includes a first wiring supplied with a power supply potential, a second wiring, a switch for controlling electrical connection between the first wiring and the second wiring, a load electrically connected to the second wiring, a transistor whose source and drain are electrically connected to the second wiring, and a power management unit having functions of controlling the conduction state of the switch and controlling a gate potential of the transistor. A channel formation region of the transistor is included in an oxide semiconductor film.
