Abstract

The semiconductor device comprising a chalcogenide phase change material. The chalcogenide material being programmed from one resistance state to another resistance state by applying a programming current to a resistor which is in thermal contact with the chalcogenide material. The semiconductor device may be used as memory element or as a programmable fuse.
