Abstract
A semiconductor device including at least one memory cell is provided. The memory cell includes: a first electrode layer; a second electrode layer; a selection element layer coupled between the first electrode layer and the second electrode layer; and an insulating layer coupled between the first electrode layer and the second electrode such that a side surface of the insulating layer is in contact with a side surface of the selection element layer, wherein the selection element layer includes an insulating material doped with a first element, and wherein the insulating layer includes the insulating material doped with the first element at a lower concentration than the selection element layer, or the insulating material not doped with the first element.
