Abstract
A variable resistance memory device includes first conductive lines extending in a first direction, second conductive lines extending in a second direction and crossing the first conductive lines in a plan view, and cell structures respectively provided at crossing points of the first conductive lines and the second conductive lines in the plan view. Each of the cell structures includes a switching pattern, a variable resistance pattern, and a first electrode provided between the switching pattern and the first conductive line, the first electrode including carbon. Each of the first conductive lines includes an upper pattern including a metal nitride in an upper portion thereof. The upper pattern is in contact with a bottom surface of the first electrode.
