(EN) Provided is a resistance change memory having a high on/off ratio. The resistance change memory of an embodiment comprises: a first electrode containing a first element; a resistance change layer formed on the first electrode and comprising an oxide of the first element; an oxygen-conducting layer which has been formed on the resistance change layer, comprises a second element and oxygen, has oxygen ion conductivity, and has a higher relative permittivity than the resistance change layer; and a second electrode formed on the oxygen-conducting layer. When the voltage between the first electrode and the second electrode is continuously raised from zero, the resistance change layer undergoes dielectric breakdown earlier than the oxygen-conducting layer.
