摘要:
According to one embodiment, a nonvolatile memory device includes a recording layer and a conductive first layer. The recording layer includes a main group element, a transition element, and oxygen. The recording layer is capable of recording information by changing reversibly between a high resistance state and a low resistance state. The first layer is made of at least one selected from a metal, a metal oxide, a metal nitride, and a metal carbide. The first layer is provided adjacent to the recording layer. The first layer includes the main group element with a concentration lower than a concentration of the main group element of the recording layer.
