Title (EN) ENHANCED STORAGE OF METADATA UTILIZING IMPROVED ERROR DETECTION AND CORRECTION IN COMPUTER MEMORY
(FR) STOCKAGE PERFECTIONNÉ DE MÉTADONNÉES UTILISANT UNE DÉTECTION ET UNE CORRECTION D'ERREURS AMÉLIORÉES DANS UNE MÉMOIRE INFORMATIQUE
Abstract:
(EN) A novel ECC scheme is disclosed that offers an error protection level that is at least the same as (if not better than) that of the conventional ECC scheme without negatively impacting latency and design complexity. Embodiments of the present disclosure utilize an ECC scheme which leaves up to extra 2B for metadata storage by changing the error detection and correction process flow. The scheme adopts an early error detection mechanism, and tailors the need for subsequent error correction based on the results of the early detection.
(FR) La présente invention concerne une nouvelle méthode CCE (code de correction d'erreurs) qui offre un niveau de protection contre les erreurs au moins égal (voire supérieur) à celui de la méthode CCE classique, sans nuire à la latence ni accroître la complexité de la conception. Des modes de réalisation de la présente invention utilisent une méthode CCE qui laisse jusqu'à 2B supplémentaires d'espace de stockage de métadonnées en modifiant le schéma de traitement de détection et de correction d'erreurs. La méthode adopte un mécanisme de détection précoce d'erreurs et adapte le besoin d'une correction d'erreurs ultérieure sur la base des résultats de la détection précoce.
