Patent abstract
A memory leveling system updates physical memory blocks, or blocks, to maintain generally even wear. The system maintains an update count for each block, incrementing a wear level count when the update count reaches a wear level threshold. The system compares a wear level of blocks to determine whether to update a block in place or move data on the block to a less-worn physical block. The system groups the blocks into wear level groups identified by a common wear level to identify blocks that are being worn at a faster or slower than average rate. If an empty block count of a least worn group drops below a threshold, the system moves data from one of the blocks in the least worn group to an empty block in a most worn group.
