Abstract
In one embodiment, a phase-change memory device has an oxidation barrier layer to protect against memory cell contamination or oxidation and a method of manufacturing the same. In one embodiment, a semiconductor memory device comprises a molding layer overlying a semiconductor substrate. The molding layer has a protrusion portion vertically extending from a top surface thereof. The device further includes a phase-changeable material pattern adjacent the protrusion portion and a lower electrode electrically connected to the phase-changeable material pattern.
