Abstract
A variable resistance memory device, and methods of manufacturing the same, include a plurality of first conductive structures extending in a first direction, a plurality of second conductive structures extending in a second direction crossing the first direction over the first conductive structures, the second conductive structures, and a plurality of memory cells that are formed at intersections at which the first conductive structures and the second conductive structures overlap each other, and each includes a selection element and a variable resistance element sequentially stacked. An upper surface of each of the first conductive structures has a width in the second direction less than a width of a bottom surface of each of the selection elements.
