Abstract
The disclosed integrated circuit includes a first and a second power supply wirings, a flip-flop circuit, and a switch element. The first and the second power supply wirings are connected to the common power supplies. The flip-flop circuit is required to hold the stored data even when the voltage supply from the power supplies to the integrated circuit is stopped. The flip-flop circuit is connected to the first power supply wiring. The switch element is a transistor, for example, and switches whether or not the voltage is supplied from the power supplies. The switch element is provided on the second power supply wiring.
