Patent attributes
A semiconductor device capable of stable operation with low power consumption is provided. A logic circuit having a circuit configuration using a transistor including an oxide semiconductor in a channel formation region is included. The logic circuit is a two-input/two-output two-wire logic circuit. Transistors included in the logic circuit each include a gate and a back gate. An input terminal is electrically connected to one of a gate and a back gate of a transistor electrically connected to a wiring for supplying a high power supply potential. An output terminal is connected to the other of the gate and the back gate of the transistor electrically connected to the wiring for supplying a high power supply potential. An output terminal is electrically connected to one of a source and a drain of a transistor electrically connected to a wiring for supplying a low power supply potential. A gate or a back gate of the transistor electrically connected to the wiring for supplying a low power supply potential is electrically connected to an input terminal.
