NON-VOLATILE STORAGE SYSTEM WITH APPLICATION-AWARE ERROR-CORRECTING CODES

摘要

A memory system (e.g., a solid state drive, or SSD) uses application-aware ECC schemes to make use of the specifics of a database schema and analytic queries. Only the fields relevant to the query are decoded, other fields are largely ignored. Integrated interleaved (II) codes and product codes approaches are described. Compared to traditional ECC schemes that decode the entire records before any fields to be used by the analytics are available, the new application-aware ECC schemes may achieve orders of magnitudes throughput improvement and/or substantially lower decoder complexity.
