1. Field of the Invention
The present invention relates to a semiconductor integrated circuit using an oxide semiconductor and a method of driving the semiconductor integrated circuit.
2. Description of the Related Art
In a semiconductor integrated circuit, a NAND circuit, a NOR circuit, an inverter circuit (NOT circuit), and the like are used in combination.
A conventional logic circuit includes a CMOS circuit in which p-channel transistors and n-channel transistors are used in a complementary combination. The conventional logic circuit loses data when power supply is stopped.
In addition, Patent Document 1 discloses a logic circuit which is formed with a CMOS circuit configuration using a spin MOSFET to maintain a nonvolatile logic function. As one example thereof, a circuit diagram of an XOR circuit from which a result of exclusive OR of one input and another input is obtained is disclosed in Patent Document 1.
