发明名称 Resistance change memory device having a variable resistance element with a recording layer electrode served as a cation source in a write or erase mode
摘要 A resistance change memory device including: a semiconductor substrate; at least one cell array formed above the semiconductor substrate to have a stack structure of a variable resistance element and an access element, the variable resistance element storing a high resistance state or a low resistance state in a non-volatile manner, the access element having such an off-state resistance value in a certain voltage range that is ten times or more as high as that in a select state; and a read/write circuit formed on the semiconductor substrate, wherein the variable resistance element includes: a recording layer formed of a composite compound containing at least one transition element and a cavity site for housing a cation ion; and electrodes formed on the opposite sides of the recording layer, one of the electrodes serving as a cation source in a write or erase mode for supplying a cation to the recording layer to be housed in the cavity site.
