Abstract
A semiconductor device includes a stacked structure of cell structures, an electrode structure, and a heating electrode. Each cell structure includes a capping layer, a selection layer, a buffer layer, a variable resistance layer, and a upper electrode layer sequentially stacked. The electrode structure is in an opening passing through the stacked structure, is electrically isolated from the buffer layer, the variable resistance layer, and the upper electrode layer, and is electrically connected to the selection layer. The heating electrode is between the variable resistance layer and the upper electrode layer and operates to transfer heat to the variable resistance layer.
