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 2):
The apparatus of  claim 1 , wherein the one or more control circuits are configured to program a selected memory cell from an erased state to a target state by applying a current pulse across the selected memory cell high enough to raise at least a portion of the phase change memory material of the selected memory cell above melting temperature thereof across the selected memory cell, an amplitude of the current pulse dependent upon the target state.
