Title
(EN) REBUILDING LOGICAL-TO-PHYSICAL ADDRESS MAPPING WITH LIMITED MEMORY
(FR) RECONSTRUCTION DE MAPPAGE D'ADRESSES LOGIQUES-PHYSIQUES AVEC MÉMOIRE LIMITÉE
Abstract
(EN) Methods, apparatuses, and systems include reading logical-to-physical (L2P) table entries from non-volatile memory into volatile memory. Upon detection of a trigger to recover L2P data that was unmerged with the L2P table entries, a copy of an L2P journal is read from non-volatile memory. The L2P journal includes the L2P data that was unmerged with the L2P table entries. One or more of the L2P table entries are updated using the L2P data from the L2P journal.
(FR) Procédés, appareils et systèmes comprenant la lecture d'entrées de table logique-physique (L2P) à partir d'une mémoire non volatile dans une mémoire volatile. Lors de la détection d'un déclencheur pour récupérer des données L2P supprimées des entrées de la table L2P, une copie d'un journal L2P est lue à partir de la mémoire non volatile. Le journal L2P comprend les données L2P qui ont été supprimées des entrées de la table L2P. Une ou plusieurs des entrées de table L2P sont mises à jour à l'aide des données L2P du journal L2P.
