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 device, comprising:\n a memory array, comprising:\n a plurality of word lines running in a horizontal direction; \n a plurality of bit lines running in a vertical direction; and \n 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; and \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 \n means for reading a data state stored in each of the multi-state memory cells; and means for writing one of a plurality of data states to each of multi-state memory cells by applying a current pulse having an amplitude dependent upon the data state to which the multi-state memory cell is to be programmed.
