A variable resistance memory device includes a substrate, a first conductive line on the substrate, the first conductive line extending in a first horizontal direction, a second conductive line extending on the first conductive line in a second horizontal direction perpendicular to the first horizontal direction, and a memory cell at an intersection between the first conductive line and the second conductive line, the memory cell having a selection element layer, an intermediate electrode layer, and a variable resistance layer, and the variable resistance layer having a shape of stairs with a concave center.
