  • Patent number: 10431270
    Abstract: Apparatuses for increasing the voltage budget window of a memory array are described. One or more pre-bias voltages may be applied across a selected cell by providing voltages to memory access lines coupled to the selected cell. The threshold voltage of the selected cell may decrease responsive to the pre-bias voltage. Conversely, threshold voltage of deselected cells coupled to only one of the memory access lines coupled to the selected cell may increase responsive to the pre-bias voltage. The decrease of the threshold voltage of the selected cell and the increase of the threshold voltage of the deselected cells may increase the voltage window of the memory array.
    Type: Grant
    Filed: December 29, 2017
    Date of Patent: October 1, 2019
    Assignee: Micron Technology, Inc.
