Abstract
Systems and methods for performing wear leveling are disclosed. In one implementation, a controller partitions a memory block into at least a first partition and a second partition. The controller utilizes the first partition of the memory block for storage of data blocks until the first partition reaches a first end of life condition. After the first partition reaches the first end of life condition, the controller utilizes the first partition for storage of data blocks associated with a compression ratio that is less than a compression threshold until the first portion reaches a second end of life condition. The controller additionally utilizes the second partition for the storage of data blocks until the second partition reaches the first end of life condition.
