Abstract: Provided are a variable resistance memory device and a method of forming the same. The variable resistance memory device may include a substrate, a plurality of bottom electrodes on the substrate, and a first interlayer insulating layer including a trench formed therein. The trench exposes the bottom electrodes and extends in a first direction. The variable resistance memory device further includes a top electrode provided on the first interlayer insulating layer and extending in a second direction crossing the first direction and a plurality of variable resistance patterns provided in the trench and having sidewalls aligned with a sidewall of the top electrode.
