  • Publication number: 20180286921
    Abstract: Described herein are multi-deck memory devices with an inverted deck. For example, in one embodiment a memory device includes a first deck of memory cells including layers of material, including a layer of storage material and a layer of selector material, and a second deck of memory cells over the first deck of memory cells, the second deck comprising layers of material in an order opposite relative to the first deck. In one such embodiment, conductive bitlines located between the first and second decks are common to both decks. Inverting the second deck can enable operating the decks symmetrically despite accessing the decks with opposite polarity voltages.

  • Publication number: 20180122860
    Abstract: Some embodiments include a construction having a first memory array deck and a second memory array deck over the first memory array deck. The second memory array deck differs from the first memory array deck in one or more operating characteristics, in pitch, and/or in one or more structural parameters; with the structural parameters including different materials and/or different thicknesses of materials. Some embodiments include a construction having a first series and a third series of access/sense lines extending along a first direction, and a second series of access/sense lines between the first and third series and extending along a second direction which crosses the first direction. First memory cells are between the first and second series of access/sense lines and arranged in a first memory array deck. Second memory cells are between the second and third series of access/sense lines and arranged in a second memory array deck.

  • Publication number: 20180040370
    Abstract: Disclosed herein is a memory cell including a memory element and a selector device. Data may be stored in both the memory element and selector device. The memory cell may be programmed by applying write pulses having different polarities and magnitudes. Different polarities of the write pulses may program different logic states into the selector device. Different magnitudes of the write pulses may program different logic states into the memory element. The memory cell may be read by read pulses all having the same polarity. The logic state of the memory cell may be detected by observing different threshold voltages when the read pulses are applied. The different threshold voltages may be responsive to the different polarities and magnitudes of the write pulses.
