Abstract
A variable resistance memory device includes memory cells arranged on a substrate and an insulating structure between the memory cells. Each of the memory cells includes a variable resistance pattern and a switching pattern vertically stacked on the substrate. The insulating structure includes a first insulating pattern between the memory cells, and a second insulating pattern between the first insulating pattern and each of the memory cells. The first insulating pattern includes a material different from a material of the second insulating pattern.
