Abstract
In a resistance change memory (ReRAM) storing data by utilizing change in resistance of a resistance change element, a lower electrode (ground-side electrode) of the resistance change element is formed of a transition metal such as Ni, and an upper electrode (positive polarity-side electrode) is configured of a noble metal such as Pt. In addition, a transition metal oxide film between the lower electrode and the upper electrode is formed of an oxide film (NiOx film) of a transition metal that is of the same kind as the transition metal constituting the lower electrode, for example.
