Abstract:
Two phase-change memory cells are formed from a first conductive via, a second conductive and a central conductive via positioned between the first and second conductive vias where a layer of phase-change material is electrically connected to the first and second conductive vias by corresponding resistive elements and insulated from the central conductive via by an insulating layer. The conductive vias each include a lower portion made of a first metal (such as tungsten) and an upper portion made of a second metal (such as copper). Drains of two transistors are coupled to the first and second conductive vias while sources of those two transistors are coupled to the central conductive via.

Claim (Index 12):
An assembly of two phase-change memory cells, comprising:\n a semiconductor substrate; a first conductive via and a second conductive via; a central conductive via located between the first and second conductive vias, wherein a lower portion of each of the first conductive via, second conductive via and central conductive via is made of a first metal and an upper portion of each of the first conductive via, second conductive via and central conductive via is made of a second metal, wherein the lower portion of the central conductive via contacts a surface of the semiconductor substrate and has a shape in the form of an elongated conductive strip extending parallel to the surface of the semiconductor substrate, and wherein all side edges of the lower portion and upper portion of each of the first conductive via, second conductive via and central conductive via are aligned with each other; a first resistive element on the first conductive via and a second resistive element on the second conductive via; and a layer of phase-change material in contact with a top portion of each of the first and second resistive elements.
