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 8):
A method of operating a memory device, the method comprising:\n applying a current to write a first state to at least one phase change memory cell of a memory cell array; conducting the current through a heating element of the at least one phase change memory cell, the heating element including a vertical portion having a thickness parallel to a first horizontal direction, a width parallel to a second horizontal direction, transverse to the first horizontal direction, and a height in a vertical direction, transverse to the first horizontal direction and the second horizontal direction, the thickness of the vertical portion being less than the width thereof; conducting the current through a volume of phase change material of the at least one phase change memory cell, without forming an electrical pathway through another volume of phase change material located in at least one dummy memory cell of the memory cell array; detecting a signal from the volume of phase change material of the at least one phase change memory cell; and applying another, different current to write a second, altered state to the at least one phase change memory cell.
