Abstract
A semiconductor device includes SRAM that stores data in an inverter loop including a CMOS inverter, transistors electrically connected to an input terminal or an output terminal of the CMOS inverter, and capacitors electrically connected to the corresponding transistors. The semiconductor device is configured to hold potentials corresponding to data at nodes between the transistors and the corresponding capacitors in a period during which supply of power to the CMOS inverter stops. In the period during which power supply stops, the potential of a wiring applying a low power supply potential is made equal to a high power supply potential to make the potentials of the input and output terminals of the CMOS inverter equal to the high power supply potential. The potentials corresponding to the data held at the nodes are applied to the input and output terminals of the CMOS inverter to restart power supply.
