  • Patent number: 11088206
    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.
