摘要： A memory cell including a memory element comprising an electrolytic insulator in contact with a conductive metal oxide (CMO) is disclosed. The CMO includes a crystalline structure and can comprise a pyrochlore oxide, a conductive binary oxide, a multiple B-site perovskite, and a Ruddlesden-Popper structure. The CMO includes mobile ions that can be transported to/from the electrolytic insulator in response to an electric field of appropriate magnitude and direction generated by a write voltage applied across the electrolytic insulator and CMO. The memory cell can include a non-ohmic device (NOD) that is electrically in series with the memory element. The memory cell can be positioned between a cross-point of conductive array lines in a two-terminal cross-point memory array in a single layer of memory or multiple vertically stacked layers of memory that are fabricated over a substrate that includes active circuitry for data operations on the array layer(s).

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 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.
