Abstract
A variable resistance memory device and a method of manufacturing the same are provided. The variable resistance memory device includes a first insulating layer formed on a semiconductor substrate, the first insulating layer having a first hole formed therein. A switching device is formed in the first hole. A second insulating layer is formed over the first insulating layer and the second insulating layer includes a second hole. A lower electrode is formed along a surface of the second insulating layer that defines the second hole. A spacer is formed on the lower electrode and exposes a portion of the surface of the lower electrode. A variable resistance material layer is formed in the second hole, and an upper electrode is formed on the variable resistance material layer.
