Patent ID: 8547721

Claim:
A resistive memory device comprising: a first electrode on a substrate; a second electrode apart from the first electrode; and a first laminated structure between the first and second electrodes including a first variable resistance layer, a first switching device, and a first intermediate electrode therebetween, wherein the first variable resistance layer includes a first variable resistance region, which is an effective variable resistance region, the first variable resistance region and the first switching device are horizontally apart from each other and not overlapped with each other, so that a reserve leakage current of the first switching device is decreased, the first intermediate electrode including a first portion extended parallel to the substrate, a second portion extended parallel to the first portion and a third portion connecting the first portion to the second portion, a lower surface and an upper surface of the first portion being horizontally apart from a lower surface and an upper surface of the second portion, and one of the first variable resistance region and the first switching device is between the first portion and the first electrode, and the other one of the first variable resistance region and the first switching device is between the second portion and the second electrode.
