Abstract:
1. A method of driving a semiconductor device comprising a logic circuit, and a programming element, the programming element comprising a transistor, a capacitor, and a node, wherein a gate of the transistor is electrically connected to the node, and wherein a first electrode of the capacitor is electrically connected to the node, the method comprising the steps of: supplying electric power to the logic circuit from a power source through the transistor while keeping the transistor in an on-state; stopping electric power supply to the logic circuit from the power source by turning off the transistor; applying a voltage between the first electrode and a second electrode of the capacitor while supplying a first potential to the second electrode of the capacitor; and supplying a second potential higher than the first potential to the second electrode of the capacitor so that a potential of the node is increased because of capacitive coupling of the capacitor.
