Abstract
A memory system or flash card may include a dynamic system-level process for the management of blocks in the different memory pools. There may be spare blocks available to the pools that are over provisioned to the pool which increases the efficiency of data compaction and helps reduce the average hot count for that pool and compensate for the grown defects. The block wear and grown defects in each memory pool may be tracked so that remaining spare blocks can be re-allocated.
