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 8):
The phase change memory device of  claim 1 , further comprising:\n a rectangular array of second memory pillar structures overlying top surfaces of the second conductive rails, wherein each second memory pillar structure comprises a vertical stack of additional structural elements including, from one end to another, a second selector-side conductive element, a second selector element, a second selector-memory conductive element, a second phase change memory element, and a second memory-side conductive element, wherein at least one structural element within the vertical stack of additional structural elements comprises another laterally constricted structural element having laterally recessed sidewalls relative to sidewalls of a respective immediately vertically underlying structural element within the vertical stack of the additional structural elements; and third conductive rails laterally extending along the first horizontal direction and overlying top surfaces of the rectangular array of second memory pillar structures.
