Abstract
A memory system may include an optimized data compaction algorithm. The compaction may include transferring only valid data from a source block to a destination block. A compaction bitmap that is maintained in random access memory ('RAM') may be populated during the compaction process. The populated bitmap may be used to copy valid fragments to the destination block.
