Abstract
A system to improve error code decoding using historical information. An example system includes storage partitioned into memory ranks, and a table to record symbols having failures for each memory rank. The system generates a memory rank score for each memory rank. The system also includes an error control decoder that uses the memory rank score when each memory rank is accessed in order to determine whether an error should be corrected or not.
