Abstract
A data storage device may include a memory and a controller that includes an error correction coding (ECC) decoder configured to operate in a plurality of decoding modes. The controller also includes a bit error rate estimator configured to determine, based on data received from the memory, bit error rate estimates for ECC codewords from the memory. The controller also includes a data path management unit configured to reorder the codewords based on the bit error rate estimates and to provide the reordered codewords to the ECC decoder.
