Abstract: A first transistor and a second transistor are stacked. The first transistor and the second transistor have a gate electrode in common. At least one of semiconductor films used in the first transistor and the second transistor is an oxide semiconductor film. With the use of the oxide semiconductor film as the semiconductor film in the transistor, high field-effect mobility and high-speed operation can be achieved. Since the first transistor and the second transistor are stacked and have the gate electrode in common, the area of a region where the transistors are disposed can be reduced.

Abstract: The storage circuit includes first and second logic circuits, first and second transistors whose channel formation regions include an oxide semiconductor, and a capacitor. The first and second transistors are connected to each other in series, and the capacitor is connected to a connection node of the first and second transistors. The first transistor functions as a switch that controls connection between an output terminal of the first logic circuit and the capacitor. The second transistor functions as a switch that controls connection between the capacitor and an input terminal of the second logic circuit. Clock signals whose phases are inverted from each other are input to gates of the first and second transistors. Since the storage circuit has a small number of transistors and a small number of transistors controlled by the clock signals, the storage circuit is a low-power circuit.

Abstract: The amount of data to be backed up and recovered is reduced when supply of power to a semiconductor device is stopped and restarted. A backup need determination circuit provided in the semiconductor device reads the kind of instruction decoded by a decoder and determines whether data needs to be backed up from a volatile register to a nonvolatile register. With a structure according to one embodiment of the present invention, it is possible to select necessary data from data used for operation in a logic circuit before the power supply is stopped and after the power supply is restarted. Data that is necessary after the power supply is restarted can be backed up from the volatile register to the nonvolatile register before the power supply is stopped. Data that is unnecessary is not backed up from the volatile register to the nonvolatile register before the power supply is stopped.
