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 20):
A non-volatile memory, comprising:\n one or more word lines formed above a substrate, running in a horizontal direction relative to the substrate; one or more bit lines formed above the substrate, running in a vertical direction relative to the substrate; and a plurality of multi-state memory cells each connected between a corresponding word line and a corresponding bit line, each of the memory cells comprising:\n a phase change memory material having a first resistivity in a first phase and a second resistivity in a second phase, the first resistivity being higher than the second resistivity; \n means for providing an additional current path adjacent to the phase change memory material having a resistivity higher than the second resistivity and lower than the first resistivity; and \n means for selecting the memory cell, the means for selecting the memory cell connected between the corresponding bit line and the corresponding word line in series with a parallel connected combination of the phase change memory material and the means for providing an additional current path.
