Patent ID: 8878589

Claim:
A semiconductor device comprising: a transistor; a first switch; a second switch; a third switch; a fourth switch; a capacitor; a load; a first line; a second line; and a third line, wherein: a first terminal of the first switch is electrically connected to the first line; one of a source and a drain of the transistor is electrically connected to a second terminal of the first switch and a first terminal of the second switch; the other of the source and the drain of the transistor is electrically connected to a first terminal of the third switch and a first terminal of the fourth switch; a gate of the transistor is electrically connected to a second terminal of the second switch and one electrode of the capacitor; the other electrode of the capacitor is directly connected to a second terminal of the fourth switch and a first terminal of the load; the other electrode of the capacitor is not directly connected to any other switch other than the fourth switch; a second terminal of the third switch is electrically connected to the second line; and a second terminal of the load is electrically connected to the third line.
