  • Patent number: 11705197
    Abstract: Methods, systems, and devices for a modified write voltage for memory devices are described. In an example, the memory device may determine a first set of memory cells to be switched from a first logic state (e.g., a SET state) to a second logic state (e.g., a RESET state) based on a received write command. The memory device may perform a read operation to determine a subset of the first set of memory cells (e.g., a second set of memory cells) having a conductance threshold satisfying a criteria based on a predicted drift of the memory cells. The memory device may apply a RESET pulse to each of the memory cells within the first set of memory cells, where the RESET pulse applied to the second set of memory cells is modified to decrease voltage threshold drift in the RESET state.

  • Publication number: 20230114440
    Abstract: Methods, systems, and devices supporting configurable resistivities for lines in a memory device, such as access lines in a memory array are described. For example, metal lines at different levels of a memory device may be oxidized to different extents in order for the lines at different levels of the memory device to have different resistivities. This may allow the resistivity of lines to be tuned on a level-by-level basis without altering the fabrication techniques and related parameters used to initially form the lines at the different levels, which may have benefits related to at least reduced cost and complexity. Lines may be oxidized to a controlled extent using either a dry or wet process.

  • Patent number: 11100984
    Abstract: An apparatus is described. The apparatus includes a cross-point non volatile memory cell array comprised of a first plurality of access lines and a second orthogonal plurality of access lines. Each of the first plurality of access lines are coupled to a first address decoder through a respective pass transistor. The pass transistor is coupled to control circuitry to bias the pass transistor into one of at least two states that include a first active state determined from a second address decoder and a second active state determined from the second address decoder.

  • Patent number: 10796761
    Abstract: Technology for a memory device is described. The memory device can include an array of memory cells and a memory controller. The memory controller can receive a request to program a memory cell within the array of memory cells. The memory controller can select a current magnitude and a duration of the current magnitude for a programming set pulse based on a polarity of access for the memory cell, a number of prior write cycles for the memory cell, and electrical distances between the memory cell and wordline/bitline decoders within the array of memory cells. The memory controller can initiate, in response to the request, the programming set pulse to program the memory cell within the array of memory cells. The selected current magnitude and the selected duration of the current magnitude can be applied during the programming set pulse.

  • Publication number: 20200211032
    Abstract: A tamperproof, counterfeiting resistant security label is envisaged. The security label includes a base layer, an adhesive layer applied atop the base layer, and a face stock positioned above the adhesive layer. The face stock essentially includes at least one scannable security element disposed thereon. The security element comprises an indicium positioned within the periphery of the face stock. The indicium is oriented with reference to the positioning of an invisible reference point situated within the periphery of the security label. The reference point, given its programmatic conceptualization and positioning is rendered invisible to naked human eye as well as to conventional scanning devices which have not been specifically pre-programmed to scan and identify otherwise invisible reference points. Positioning of the reference point and the positioning of the indicium put together forms a non-apparent, signature unique to the security label.

  • Publication number: 20190206491
    Abstract: Examples may include techniques to mitigate voltage threshold drift over a period of time that may cause selection failure for selecting memory cells of a memory device. A snap-back event detection is used to determine whether a selected memory cell has been selected for at least a first refresh write operation using one or more selection bias voltages. A subsequent refresh write operation may be implemented based on this determination.
