An electronic device which includes, a couple of first conduction regions which are capable of confining carriers, a second conduction region having a higher energy level than those of the first conduction regions, and a first electrode for impressing a voltage on the first conduction regions, wherein when a voltage is impressed via the first electrode between the couple of first conduction regions, carriers are caused to move due to a tunneling effect from one of the first conduction regions via the second conduction region to the other of the first conduction regions, and when the voltage impressed between the couple of first conduction regions is removed, carriers are confined mainly in the one of the first conduction regions.
