Abstract:
A phase change memory device includes first conductive rails laterally extending along a first horizontal direction over a substrate, a rectangular array of memory pillar structures overlying top surfaces of the first conductive rails, and second conductive rails laterally extending along a second horizontal direction and overlying top surfaces of the rectangular array of memory pillar structures. Each memory pillar structure includes a vertical stack of structural elements including, from one end to another, a selector-side conductive element, a selector element, a selector-memory conductive element, a phase change memory element, and a memory-side conductive element. At least one structural element within the vertical stack is a laterally constricted structural element having laterally recessed sidewalls relative to sidewalls of a respective immediately vertically underlying structural element.

Claim (Index 20):
A method of programming a memory cell of the phase change memory device of  claim 1  from a set state to a reset state, the method comprising applying a reset voltage through a selected one of the first memory pillar structures to convert only an upper part of the first phase change memory element of the selected one of the first memory pillar structures from a crystalline state to an amorphous state to reset the memory cell located in the selected one of the first memory pillar structures to the reset state, while a lower part of the phase change memory element remains in the crystalline state.
