Abstract

A switching device includes a first electrode, a switching layer having a non-memory characteristic, and a second electrode that are disposed over a substrate. The switching layer includes an oxide of a first atom or a nitride of the first atom, and a second atom is doped in the oxide or the nitride. The second atom forms a trap site trapping a conductive carrier in the switching layer when a voltage having an absolute value that is smaller than an absolute value of a predetermined threshold voltage is applied between the first and the second electrodes. The second atom forms a moving path through which the conductive carrier moves between the first electrode and the second electrode when a voltage having an absolute value that is greater than an absolute value of a predetermined threshold voltage is applied between the first and the second electrodes.
