Abstract

A data storage device includes a memory including a plurality of storage elements. The data storage device further includes a controller coupled to the memory. The controller includes an error correction code (ECC) engine. The controller further includes a reliability engine configured to access historical bit error data. The historical bit error data includes a first count of bit errors associated with a first set of storage elements of the plurality of storage elements. The reliability engine is configured to generate reliability information based on the historical bit error data and to provide the reliability information to the ECC engine.
