Abstract:
A non-volatile memory uses phase change memory (PCM) cells in a three dimensional vertical cross-point structure, in which multiple layers of word lines run in a horizontal direction and bit lines run in a vertical direction. The memory cells are located in a recessed region of the word lines and are separated from the bit line by an ovonic threshold switch. A surfactant lining of the word line recess in which the phase change memory material is placed improves stability of the resistance state of the memory cells, allowing for improved multi-state operation.

Claim (Index 4):
The memory structure of  claim 1 , further comprising:\n a surfactant layer lining the pocket recessed from the bit line, the surfactant layer separating the phase change memory material from the word line layers and the respective dielectric layers between which the word line layers are formed.
