Claim 18:
19. A data writing method performed by a storage device that comprises a resistance change memory element including a first electrode, a second electrode, a resistance change layer between the first and second electrodes and including at least two elements selected from a group consisting of germanium (Ge), antimony (Sb), and tellurium (Te), and a first layer between the first electrode and the resistance change layer and including at least one of silicon (Si) or germanium (Ge), the method comprising:
applying a first voltage having a first polarity to the resistance change memory element; and
after applying the first voltage, applying a write voltage having a second polarity opposite to the first polarity to the resistance change memory element,
wherein the first layer further contains nitrogen (N).
