Abstract

Provided is a resistance-switching device. The resistance-switching device includes a first wiring including an aluminum oxide surface layer, and a second wiring including a carbon-containing surface layer in contact with the aluminum oxide surface layer. Electrochemical reaction products according to a reaction of aluminum oxide and carbon are generated or destroyed at a contact interface between the aluminum oxide surface layer and the carbon-containing surface layer according to a voltage or a current applied to the first wiring and the second wiring, and low resistance and high resistance are provided between the first wiring and the second wiring by the generation or destruction of the electrochemical reaction products.
