摘要： A memory cell including conductive oxide electrodes is disclosed. The memory cell includes a memory element operative to store data as a plurality of resistive states. The memory element includes a layer of a conductive metal oxide (CMO) (e.g., a perovskite) in contact with an electrode that may comprise one or more layers of material. At least one of those layers of material can be a conductive oxide (e.g., a perovskite such as LaSrCoO3-LSCoO or LaNiO3-LNO) that is in contact with the CMO. The conductive oxide layer can be selected as a seed layer operative to provide a good lattice match with and/or a lower crystallization temperature for the CMO. The conductive oxide layer may also be in contact with a metal layer (e.g., Pt). The memory cell additionally exhibits non-linear IV characteristics, which can be favorable in certain arrays, such as non-volatile two-terminal cross-point memory arrays.

摘要： A treated conductive element is provided. A conductive element can be treated by depositing either a reactive metal or a very thin layer of material on the conductive element. The reactive metal (or very thin layer of material) would typically be sandwiched between the conductive element and an electrode. The structure additionally exhibits non-linear IV characteristics, which can be favorable in certain arrays.

摘要： A memory using a tunnel barrier that has a variable effective width is disclosed. A memory element includes a tunneling barrier and a conductive material. The conductive material typically has mobile ions that either move towards or away from the tunneling barrier in response to a voltage across the memory element. A low conductivity region is either formed or destroyed. It can be formed by either the depletion or excess ions around the tunneling barrier, or by the mobile ions combining with complementary ions. It may be destroyed by either reversing the forming process or by reducing the tunneling barrier and injecting ions into the conductive material. The low conductivity region increases the effective width of the tunnel barrier, making electrons tunnel a greater distance, which reduces the memory element's conductivity. By varying conductivity multiple states can be created in the memory cell.

摘要： A conductive memory stack is provided. The memory stack includes a bottom electrode, a top electrode and a multi-resistive state element. The multi-resistive state element is sandwiched between the electrodes such that the top face of the bottom electrode is in contact with the multi-resistive state element's bottom face and the bottom face of the top electrode is in contact with the multi-resistive state element's top face. The bottom electrode, the top electrode and the multi-resistive state element all have sides that are adjacent to their faces. Furthermore, the sides are at least partially covered by a sidewall layer.
