Abstract
A memory device may include a substrate, a first conductive line on the substrate and extending in a first direction, a second conductive line over the first conductive line and extending in a second direction crossing the first direction, a third conductive line over the second conductive line and extending in the first direction, a first memory cell at an intersection of the first conductive line and the second conductive line and including a first selection element layer and a first variable resistance layer, and a second memory cell at an intersection of the second conductive line and the third conductive line and including a second selection element layer and a second variable resistance layer. A first height of the first selection element layer in a third direction perpendicular to the first and second directions is different than a second height of the second selection element layer in the third direction.
