ABSTRACT:
Non-volatile memory devices for providing selective compaction verification and/or selective compaction to facilitate a tightening of the distribution of threshold voltages in memory devices utilizing a NAND architecture. By providing for compaction verification and/or compaction on less than all word lines of a NAND string, increased tightening of the distribution may be achieved over prior methods performed concurrently on all word lines of a NAND string.
