Abstract:
A variable resistance memory device and a method of manufacturing the same are provided. The variable resistance memory device may include a multi-layered insulating layer formed on a semiconductor substrate, on which a lower electrode is formed. The multi-layered insulating layer may include a first hole and a second hole, concentrically formed therein, to expose the lower electrode, wherein a diameter of the first hole is larger than a diameter of the second hole. A variable resistance material layer may be formed in the second hole to contact the lower electrode, and an upper electrode may be formed in the first hole to contact the variable resistance material layer.
