Abstract
To provide a semiconductor device that can reduce standby power.SOLUTION: A transistor including an oxide semiconductor as an active layer is used as a switching element, and by this switching element, the supply of power source voltage to a circuit included in an integrated circuit is controlled. Specifically, when the circuit is in an operation state, the power source voltage is supplied to the circuit by the switching element and when the circuit is in a stop state, the supply of the power source voltage to the circuit is stopped by the switching element. The circuit to which the power source voltage is supplied includes one or more semiconductor elements corresponding to the minimum unit of the integrated circuit, such as a transistor, a diode, a capacitor, a resistor, or an inductor formed using semiconductor. The semiconductor included in the semiconductor element includes silicon with crystallinity (crystalline silicon), specifically, microcrystalline silicon, polycrystalline silicon, and single-crystal silicon.SELECTED DRAWING: Figure 1
