  • Patent number: 9570515
    Abstract: 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.

  • Publication number: 20150132917
    Abstract: Embodiments relate generally to semiconductors and memory technology, and more particularly, to systems, integrated circuits, and methods to implement a memory architecture that includes local bit lines for accessing subsets of memory elements, such as memory elements based on third dimensional memory technology. In at least some embodiments, an integrated circuit includes a cross-point memory array formed above a logic layer. The cross-point memory array includes X-lines and Y-lines, of which at least one Y-line includes groups of Y-line portions. Each of the Y-line portions can be arranged in parallel with other Y-line portions within a group of the Y-line portions. Also included are memory elements disposed between a subset of the X-lines and the group of the Y-line portions. In some embodiments, a decoder is configured to select a Y-line portion from the group of Y-line portions to access a subset of the memory elements.

  • Patent number: 8569160
    Abstract: Device fabrication is disclosed, including forming a first part of a device at a first fabrication facility as part of a front-end-of-the-line (FEOL) process, the first part of the device comprising a base wafer formed by FEOL processing, and subsequently performing one or more back-end-of-the-line (BEOL) processes at a second fabrication facility to form an IC, the one or more BEOL processes comprising finishing the forming of the device (e.g., an IC including memory) by depositing one or more memory layers on the base wafer. FEOL processing can be used to form active circuitry die (e.g., CMOS circuitry on a Si wafer) and BEOL processing can be used to form on top of each active circuitry die, one or more layers of cross-point memory arrays formed by thin film processing technologies that may or may not be compatible with or identical to some or all of the FEOL processes.
