摘要: A memory cell including a memory element and a non-ohmic device (NOD) that are electrically in series with each other is disclosed. The NOD comprises a semiconductor based selection device operative to electrically isolate the memory element from a range of voltages applied across the memory cell that are not read voltages operative read stored data from the memory element or write voltages operative to write data to the memory element. The selection device may comprise a pair of diodes that are electrically in series with each other and disposed in a back-to-back configuration. The memory cell may be fabricated over a substrate (e.g., a silicon wafer) that includes active circuitry. The selection device and the semiconductor materials (e.g., poly-silicon) that form the selection device are fabricated above the substrate and are integrated with other thin film layers of material that form the memory cell.

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 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.
