Abstract
According to one embodiment, a storage device includes first electrodes, second electrodes, a resistance change layer provided between the first electrodes and the second electrodes, and ion metal particles that are formed in an island form between the first electrodes and the resistance change layer and that contain a metal movable inside the resistance change layer. The first electrodes and the second electrodes are formed of a material which is more unlikely to be ionized as compared to the metal, and the first electrodes are in contact with the resistance change layer in an area around the ion metal particles.
