Error correction code (ECC) selection using probability density functions of error correction capability in storage controllers with multiple error correction codes

摘要

An apparatus includes an error correction code circuit and an error correction code selection circuit. The error correction code circuit may be configured to encode and decode data using any of a plurality of error correction codes. The error correction code selection circuit may be configured to control which of the plurality of error correction codes is used by the error correction code circuit to encode and decode data responsive to one or more reliability statistics and predetermined data characterizing distribution properties of each of the plurality of error correction codes.
