Abstract:
Non-volatile memory elements, memory devices including the same, and methods for operating and manufacturing the same may include a memory layer between a first electrode and a second electrode spaced apart from the first electrode. The memory layer may include a first material layer and a second material layer, and may have a resistance change characteristic due to movement of ionic species between the first material layer and the second material layer. At least the first material layer of the first and second material layers may be doped with a metal.
