Abstract

A variable resistance memory device may include: a first electrode layer; a selection device layer on the first electrode layer, the selection device layer including a chalcogenide switching material consisting essentially of germanium (Ge), selenium (Se), and antimony (Sb), wherein a content of the Ge is less than a content of the Se based on an atomic weight; a second electrode layer on the selection device layer; a variable resistance layer on the second electrode layer, the variable resistance layer including a chalcogenide material; and a third electrode layer on the variable resistance layer.
