  • Patent number: 11942164
    Abstract: Devices and techniques are disclosed herein to provide a number of different bias signals to each of multiple signal lines of an array of memory cells, each bias signal having an overdrive voltage above a target voltage by a selected increment and an overdrive period, to determine settling times of each of the multiple signal lines to the target voltage for the number of different bias signals, to determine a functional compensation profile for an array of memory cells comprising a relationship between the different bias signals and the determined settling times of the multiple signal lines.
    Type: Grant

  • Patent number: 11557351
    Abstract: A device includes a memory array and a sense circuit coupled with the memory array. The sense circuit includes a sense node coupled with a data line of the memory array. A first sensing path includes a first transistor having a first gate coupled with the sense node. A second sensing path includes a second transistor having a second gate coupled with the sense node. A first threshold voltage of the first transistors differs from a second threshold voltage of the second transistor by a threshold voltage gap.

  • Patent number: 11158391
    Abstract: Devices and techniques are disclosed herein to compensate for variance in one or more electrical parameters across multiple signal lines of an array of memory cells. A compensation circuit can provide a bias signal to a first one of the multiple signal lines, the bias signal having an overdrive voltage greater than a target voltage by a selected increment for a selected overdrive period.
