MEMORY DEVICE PROGRAM WINDOW ADJUSTMENT |
摘要 |
In one or more embodiments, a memory device is disclosed as having an adjustable programming window having a plurality of programmable levels. The programming window is moved to compensate for changes in reliable program and erase thresholds achievable as the memory device experiences factors such as erase/program cycles that change the program window. The initial programming window is determined prior to an initial erase/program cycle. The programming levels are then moved as the programming window changes, such that the plurality of programmable levels still remain within the program window and are tracked with the program window changes.
