Maximum-likelihood decoder in a memory controller for synchronization

摘要

Described herein are apparatus, system, and method for data synchronization via a maximum-likelihood decoder in a memory controller. The method comprises receiving a constrained codeword from a non-volatile memory (NVM) via a channel, the constrained codeword including an appended bit-stream; and decoding the received constrained codeword by reconstructing the appended bit-stream and invoking a synchronization procedure that applies a maximum-likelihood (ML) estimator to estimate locations of any insertion, deletion, or error in the reconstructed appended bit-stream.
