Abstract: To reduce power consumption of a computer or the like, a nonvolatile memory divided into a plurality of segments is applied to main memory used for virtual storage management.

Abstract: A semiconductor device capable of simply performing power gating and a driving method thereof are provided. Power gating is started passively (automatically in the case of satisfying predetermined conditions). Specifically, the semiconductor device includes a transistor for selecting whether a power source voltage is supplied or not to a functional circuit. The power gating is started by turning off the transistor in the case where a voltage between a source and a drain is less than or equal to a predetermined voltage. Therefore, complicated operation is not needed at the time of starting power gating. Specifically, it is possible to start power gating without a process for predicting the timing at which an arithmetic operation performed in the functional circuit is terminated. As a result, it is possible to start power gating easily.

Abstract: An object is to reduce parasitic capacitance of a signal line included in a liquid crystal display device. A transistor including an oxide semiconductor layer is used as a transistor provided in each pixel. Note that the oxide semiconductor layer is an oxide semiconductor layer which is highly purified by thoroughly removing impurities (hydrogen, water, or the like) which become electron suppliers (donors). Thus, the amount of leakage current (off-state current) can be reduced when the transistor is off. Therefore, a voltage applied to a liquid crystal element can be held without providing a capacitor in each pixel. In addition, a capacitor wiring extending to a pixel portion of the liquid crystal display device can be eliminated. Therefore, parasitic capacitance in a region where the signal line and the capacitor wiring intersect with each other can be eliminated.
