Patent ID: 7911233

Claim:
A semiconductor device comprising: a first transistor; a second transistor; a switch; and a capacitor, wherein the first transistor includes a gate terminal, a first terminal, and a second terminal; wherein the second transistor includes a gate terminal, a first terminal, and a second terminal; wherein the gate terminal of the first transistor and the first terminal of the first transistor are electrically connected via the switch; wherein the gate terminal of the first transistor is electrically connected to the gate terminal of the second transistor; wherein the second terminal of the first transistor is electrically connected to the first terminal of the second transistor; wherein the gate terminal of the first transistor is electrically connected to one terminal of the capacitor; wherein the second terminal of the second transistor is electrically and directly connected to the other terminal of the capacitor; and wherein a means for short-circuiting between the first terminal of the first transistor and the second terminal of the first transistor or between the first terminal of the second transistor and the second terminal of the second transistor is included.
