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 and a second layer. The first layer is formed of a first material. The second layer is on the first layer and formed of a second material having a density different from a density of the first material. The first conductive element and a second conductive element are located on the variable resistance layer and spaced apart from each other in order to form a current path in the variable resistance layer. The current path is in a direction perpendicular to a direction in which the first layer and the second layer are stacked.
