Abstract

Les fichiers de données d'un système hôte sont directement écrits dans un système de mémoire flash à gros bloc effaçage avec une seule identification par fichier et des décalages de données dans le fichier, mais sans utiliser d'adresses logiques intermédiaires ou l'espace pour adresses virtuelle de la mémoire. Les informations du répertoire indiquant où les fichiers sont stockés dans la mémoire sont conservées dans le système de mémoire par son contrôleur plutôt que par son hôte. Chaque fichier de données est identifié de manière unique dans le répertoire des fichiers qui pointe sur les entrées d'une table des index de fichiers de groupes de données qui constituent le fichier et leur emplacement physique de stockage dans la mémoire.
