Abstract
To provide a resistance change element which does not require a forming process and enables reduction of power consumption and miniaturization of the element, and to provide a method for producing it. A resistance change elementaccording to an embodiment of the present invention includes a bottom electrode layer, a top electrode layerand an oxide semiconductor layer. The oxide semiconductor layerhas a first metal oxide layerand a second metal oxide layer. The first metal oxide layeris formed between the bottom electrode layerand the top electrode layer, and in ohmic contact with the bottom electrode layer. The second metal oxide layeris formed between the first metal oxide layerand the top electrode layer, and in ohmic contact with the top electrode layer.
