Abstract
A variable resistance memory device includes a variable resistance layer, a first conductive element, and a second conductive element. The variable resistance layer includes a first layer including a first material and a second layer on the first layer and the second layer including a second material. The second material has a different valence than a valence of the first material. The first conductive element and the second conductive element are on the variable resistance layer and separated from each other to form an electric current path in the variable resistance layer in a direction perpendicular to a direction in which the first layer and the second layer are stacked.
