    Abstract: Molybdenum oxide can be used to form switching elements in a resistive memory device. The atomic ratio of oxygen to molybdenum can be between 2 and 3. The molybdenum oxide exists in various Magneli phases, such as Mo13O33, Mo4O11, Mo17O47, Mo8O23, or Mo9O26. An electric field can be established across the switching layers, for example, by applying a set or reset voltage. The electric field can cause movement of the oxygen charges, e.g., O2− ions, changing the composition profile of the switching layers, forming bistable states, including a high resistance state with MoO3 and a low resistance state with MoOx (x

    Abstract: A method for reducing the leakage current in DRAM Metal-Insulator-Metal capacitors includes forming a capacitor stack including an oxygen donor layer inserted between the dielectric layer and at least one of the two electrode layers. In some embodiments, the dielectric layer may be doped with an oxygen donor dopant. The oxygen donor materials provide oxygen to the dielectric layer and reduce the concentration of oxygen vacancies, thus reducing the leakage current.

    Abstract: An internal electrical field in a resistive memory element can be formed to reduce the forming voltage. The internal electric field can be formed by incorporating one or more charged layers within the switching dielectric layer of the resistive memory element. The charged layers can include adjacent charge layers to form dipole layers. The charged layers can be formed at or near the interface of the switching dielectric layer with an electrode layer. Further, the charged layer can be oriented with lower valence substitution side towards lower work function electrode, and higher valence substitution side towards higher work function electrode.

    Abstract: A YBCO-based conductive material can be used as an electrode, which can contact a dielectric such as a high k dielectric. Alternatively, a material with a narrow conduction band can be used as an electrode, which can contact a dielectric such as a high k dielectric. By aligning the dielectric with the band gap of the YBCO-based electrode or with the band gap of the narrow-band conductive material electrode, e.g., the conduction band minimum of the dielectric falls into one of the band gaps of the YBCO-based or narrow-band conductive material, thermionic leakage through the dielectric can be reduced, since the excited electrons or holes in the electrode would need higher thermal excitation energy to overcome the band gap before passing through the dielectric layer.

    Abstract: Provided are method for determining switching conditions for production memory cells based on dopant flux during set and reset operations. One group of test memory cells, which are representative of the production memory cells, is subjected to a prolonged application of a set voltage, while another group is subjected to a prolonged application of a reset voltage. Different durations may be used for different cells in each group. A dopant concentration profile of a test component in each cell is determined for both groups. One cell from each group may be identified such that the changes in the dopant concentration profiles in these two identified cells are complementary. The profile complementarity indicates that these two identified cells had a similar dopant flux during voltage applications. Durations of set and reset voltage applications for these two cells may be used to determine switching conditions for production memory cells.
