Abstract
To remedy short term data retention issues, a non-volatile memory performs a multi-pass programming process to program data into a set of non-volatile memory cells and identifies non-volatile memory cells that experienced downward threshold voltage drift after a first pass of the multi-pass programming process and prior to a final pass of the multi-pass programming process. The final pass of the multi-pass programming process comprises programming non-volatile memory cells not identified to have experienced the downward threshold voltage drift to a set of final target threshold voltages and purposefully overprogramming non-volatile memory cells identified to have experienced the downward threshold voltage drift to threshold voltages greater than respective final target threshold voltages by one or more offsets.
