Abstract: A non-volatile memory attempts to read a data set from a plurality of non-volatile memory cells in multiple threshold voltages distributions and determines that the data set was not read successfully due to there being too many errors in the data read. In response to determining that the data set was not read successfully, the system identifies memory cells storing error bits that are in upper tails and lower tails of the threshold voltages distributions. To reduce the number of errors, memory cells storing error bits that are in upper tails have their threshold voltages reduced by bit level erase and memory cells storing error bits that are in lower tails their threshold voltages increased to move the memory cells closer to the center of their respective threshold voltages distributions by bit level program.
