    摘要: A signal processing circuit whose power consumption can be suppressed is provided. In a period during which a power supply voltage is not supplied to a storage element, data stored in a first storage circuit corresponding to a nonvolatile memory can be held by a first capacitor provided in a second storage circuit. With the use of a transistor in which a channel is formed in an oxide semiconductor layer, a signal held in the first capacitor is held for a long time. The storage element can accordingly hold the stored content (data) also in a period during which the supply of the power supply voltage is stopped. A signal held by the first capacitor can be converted into the one corresponding to the state (the on state or off state) of the second transistor and read from the second storage circuit. Consequently, an original signal can be accurately read.

    摘要: An integrated circuit which can be switched to a resting state and can be returned from the resting state rapidly is provided. An integrated circuit whose power consumption can be reduced without the decrease in operation speed is provided. A method for driving the integrated circuit is provided. The integrated circuit includes a first flip-flop and a second flip-flop including a nonvolatile memory circuit. In an operating state in which power is supplied, the first flip-flop retains data. In a resting state in which supply of power is stopped, the second flip-flop retains data. On transition from the operating state into the resting state, the data is transferred from the first flip-flop to the second flip-flop. On return from the resting state to the operating state, the data is transferred from the second flip-flop to the first flip-flop.
