A method of performing wear-leveling on a memory implemented by a memory system, comprises determining, by a processor coupled to the receiver and the memory, a circular shifter offset based on a write count of the first portion of the memory, and writing, by the memory, the plurality of user bits and the plurality of error-correcting code (ECC) bits to a plurality of memory cells within a first portion of the memory and a second portion of the memory based on the circular shifter offset.
