    Abstract: In a first aspect, a metal-insulator-metal (“MIM”) stack is provided that includes a first conductive layer, a resistivity-switching layer having a metal oxide layer formed above the first conductive layer, a material layer between the first conductive layer and the resistivity-switching layer, and a second conductive layer above the resistivity-switching layer. The first conductive layer includes a multi-layer metal-silicide stack, and the material layer has a Gibbs free energy of formation per O between about −3 and −6 eV. A memory cell may be formed from the MIM stack. Numerous other aspects are provided.

    Abstract: Non-volatile storage elements having a reversible resistivity-switching element and techniques for fabricating the same are disclosed herein. The reversible resistivity-switching element may be formed by depositing an oxygen diffusion resistant material (e.g., heavily doped Si, W, WN) over the top electrode. A trap passivation material (e.g., fluorine, nitrogen, hydrogen, deuterium) may be incorporated into one or more of the bottom electrode, a metal oxide region, or the top electrode of the reversible resistivity-switching element. One embodiment includes a reversible resistivity-switching element having a bi-layer capping layer between the metal oxide and the top electrode. Fabricating the device may include depositing (un-reacted) titanium and depositing titanium oxide in situ without air break. One embodiment includes incorporating titanium into the metal oxide of the reversible resistivity-switching element. The titanium might be implanted into the metal oxide while depositing the metal oxide, or after deposition of the metal oxide.
