Patent ID: 7358789

Claim:
A semiconductor device comprising: a first transistor having a gate electrode to which a first signal is inputted and a first terminal to which a second signal is inputted; a second transistor having a gate electrode to which the second signal is inputted and a first terminal to which the first signal is inputted; a third transistor having a first terminal to which a predetermined potential is inputted and a second terminal connected to the second terminal of the first transistor; and a fourth transistor having a gate electrode connected to a gate electrode of the third transistor, a first terminal to which a predetermined potential is inputted, a second terminal connected to a second terminal of the second transistor, the gate electrode and the second terminal thereof are connected to each other, wherein the first transistor and the second transistor are p-channel transistors and the third transistor and the fourth transistor are n-channel transistors, wherein the gate electrode of the first transistor is directly connected to the first terminal of the second transistor, and wherein the gate electrode of the second transistor is directly connected to the first terminal of the first transistor.
