Abstract
An electronic device includes a semiconductor memory. The semiconductor memory includes a vertical electrode layer formed over a substrate and extending in a vertical direction substantially perpendicular to a surface of the substrate; an interlayer dielectric layer and a structure formed over the substrate and alternately stacked along the vertical electrode layer, wherein the structure includes a horizontal electrode layer and a base layer which is conductive and located over or under the horizontal electrode layer; a variable resistance layer interposed between the vertical electrode layer and the base layer, and including a common element with the base layer; and a groove interposed between the vertical electrode layer and the horizontal electrode layer and insulating the vertical electrode layer and the horizontal electrode layer from each other.
