Abstract:
Phase change memory apparatuses include memory cells including phase change material, bit lines electrically coupled to aligned groups of at least some of the memory cells, and heating elements electrically coupled to the phase change material of the memory cells. The heating elements include vertical portions extending in a bit line direction. Additional phase change memory apparatuses include dummy columns positioned between memory columns and base contact columns. The dummy columns include phase change memory cells and lack heating elements coupled to the phase change memory cells thereof. Additional phase change memory apparatuses include heating elements operably coupled to phase change memory cells. An interfacial area between the heating elements and the phase change memory cells has a length that is independent of a bit line width. Methods relate to forming such phase change memory apparatuses.

Claim (Index 1):
A method of operating a memory device, the method comprising:\n applying a first current to a volume of phase change material to write a first state to a memory cell, wherein applying the first current comprises:\n applying the first current to an electrode of the memory cell, the memory cell sharing a common access line with adjacent memory cells, the common access line including elongated portions extending in a first horizontal direction, and the memory cell sharing a common data line with adjacent memory cells, the common data line including elongated portions extending in a second horizontal direction, transverse to the first horizontal direction; \n transmitting the first current to a heating element including a vertical portion having a thickness parallel to the first horizontal direction, a width parallel to the second horizontal direction, and a height in a vertical direction, transverse to the first horizontal direction and the second horizontal direction, wherein the thickness of the vertical portion parallel to the first horizontal direction is less than the width of the vertical portion parallel to the second horizontal direction; and \n transmitting the first current to the volume of phase change material; and \n applying a second, different current to the volume of phase change material to write a second state to the memory cell.
