Abstract:
In operation, respective lifetime expectancy scores are calculated for each of a plurality of blocks of a memory based on a respective count percentage of free space of each of the blocks. The blocks are recycled based on at least some of the life expectancy scores. A total amount of the blocks that are re-written is minimized while equalizing lifetime expectancy score variation between the blocks.
