  • Boundary word line voltage shift
    Patent number: 10559366
    Abstract: Apparatuses, systems, methods, and computer program products for dynamically determining boundary word line voltage shift are presented. An apparatus includes an array of non-volatile memory cells and a controller. A controller includes a trigger detection component that is configured to detect a trigger condition associated with a last programmed word line of a partially programmed erase block of an array of non-volatile memory cells. A controller includes a voltage component that is configured to determine a read voltage threshold for a last programmed word line of a partially programmed erase block in response to a trigger condition. A controller includes a voltage shift component that is configured to calculate, dynamically, a read voltage threshold shift for a last programmed word line based on a determined read voltage threshold for the last programmed word line and a baseline read voltage threshold.
