ABSTRACT:
A ring shaped heater surrounds a chalcogenide region along the length of a cylindrical solid phase portion thereof defining a change phase memory element. The chalcogenide region is formed in a sub-lithographic pore, so that a relatively compact structure is achieved. Furthermore, the ring contact between the heater and the cylindrical solid phase portion results in a more gradual transition of resistance versus programming current, enabling multilevel memories to be formed.
