Method of fabricating a nonvolatile memory device made of electric resistance material

摘要

A nonvolatile memory device using a resistance material and a method of fabricating the same are provided. The nonvolatile memory device includes a switching element, and a data storage part electrically connected to the switching element. In the data storage part, a lower electrode is connected to the switching element, and an insulating layer is formed on the lower electrode to a predetermined thickness. The insulating layer has a contact hole exposing the lower electrode. A data storage layer is filled in the contact hole and the data storage layer is formed of transition metal oxide. An upper electrode is formed on the insulating layer and the data storage layer.
