Method of driving semiconductor device

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 to the second electrode of the capacitor while the node is in floating.

A method of driving a semiconductor device comprising a logic circuit, a first transistor, a second transistor, and a capacitor, wherein one of a source and a drain of the first transistor is electrically connected to a gate of the second transistor, wherein a first electrode of the capacitor is electrically connected to the gate of the second transistor, wherein one of a source and a drain of the second transistor is electrically connected to the logic circuit, and wherein the other of the source and the drain of the second transistor is electrically connected to a power source, the method comprising the steps of:

• applying a voltage between the first electrode and a second electrode of the capacitor while keeping the first transistor in an on-state and supplying a first potential to the second electrode of the capacitor;
• turning off the first transistor after applying the voltage between the first electrode and the second electrode of the capacitor;
• and
• supplying a second potential to the second electrode of the capacitor while keeping the first transistor in an off-state.
