Claim 19:
20. A storage device, comprising:
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); and

a signal application circuit configured to apply a first voltage having a first polarity opposite to a second polarity of a write voltage to the resistance change memory element before applying the write voltage to the resistance change memory element,
wherein the resistance change memory element further includes a second layer between the second electrode and the resistance change layer and including at least one of silicon (Si) or germanium (Ge).
