Abstract:
1. A method of forming a memory device, the method comprising: removing material disposed between a first memory cell comprising a phase change material and a second memory cell comprising a phase change material to form a cavity extending from the first memory cell to the second memory cell, comprising: forming a dielectric material extending over and between the first memory cell and the second memory cell to at least substantially enclose the cavity extending from the first memory cell to the second memory cell; and forming a passivation material separate from the dielectric material on an exposed portion of the electrode and the phase change material of the first memory cell and on an exposed portion of the electrode and the phase change material of the second memory cell such that the cavity extends from a portion of the passivation material on the first memory cell to another portion of the passivation material on the second memory cell.
