    Abstract: Some embodiments include methods of forming memory cells. Chalcogenide is formed over a plurality of bottom electrodes, and top electrode material is formed over the chalcogenide. Sacrificial material is formed over the top electrode material. A plurality of memory cell structures is formed by etching through the sacrificial material, top electrode material and chalcogenide. Each of the memory cell structures has a cap of the sacrificial material thereover. The etching forms polymeric residue over the sacrificial material caps, and damages chalcogenide along sidewalls of the structures. The sacrificial material is removed with an HF-containing solution, and such removes the polymeric residue off of the memory cell structures. After the sacrificial material is removed, the sidewalls of the structures are treated with one or both of H2O2 and HNO3 to remove damaged chalcogenide from the sidewalls of the memory cell structures.

    Abstract: A magnetic cell structure including a nonmagnetic filament contact, and methods of fabricating the structure are provided. The magnetic cell structure includes a free layer, a pinned layer, an insulative layer between the free and pinned layers, and a nonmagnetic filament contact in the insulative layer which electrically connects the free and pinned layers. The nonmagnetic filament contact is formed from a nonmagnetic source layer, also between the free and pinned layers. The filament contact directs a programming current through the magnetic cell structure such that the cross sectional area of the programming current in the free layer is less than the cross section of the structure. The decrease in the cross sectional area of the programming current in the free layer enables a lower programming current to reach a critical switching current density in the free layer and switch the magnetization of the free layer, programming the magnetic cell.
