Abstract
Provided are a variable resistive memory device and a method of fabricating the same. The variable resistive memory device includes an interlayer insulating film having an opening therein, the opening exposing a surface of a first electrode which is disposed at a bottom of the opening. A variable resistive layer is formed in the opening and a second electrode is formed on the variable resistive layer. The variable resistive layer has a sidewall that is separated from an inner side surface of the opening to define a gap between the sidewall of the variable resistive layer and the inner side surface of the opening.
