Title (EN) ORGANIZATION OF BLOCKS WITHIN A NONVOLATILE MEMORY UNIT TO EFFECTIVELY DECREASE SECTOR WRITE OPERATION TIME
(FR) ORGANISATION DE BLOCS DANS UNE UNITE DE MEMOIRE NON VOLATILE PERMETTANT DE REDUIRE EFFICACEMENT LA DUREE D'UNE OPERATION D'ECRITURE SUR UN SECTEUR
Abstract:
(EN) An embodiment of the present invention includes a nonvolatile memory system for storing sector information in storage locations (232) within nonvolatile memory (16) organized into blocks, a plurality of blocks defining a super block and each block having a predetermined plurality of sectors. The nonvolatile memory system includes a controller (14) for shifting sector information to a first (210) and a second block (216) of a particular super block (204) and writing sector information to the first block (210) of the particular super block, wherein shifting to the second block (216) occurs entirely during the writing to the first block thereby decreasing the time required to perform write operations to blocks and increasing overall system performance.
(FR) Selon un mode de réalisation, l'invention concerne un système de mémoire non volatile permettant de stocker des informations sectorielles dans des emplacements de stockage (232), dans une mémoire non volatile (16) organisée en blocs, une pluralité de blocs définissant un super bloc, et chaque bloc possédant une pluralité de secteurs prédéterminés. Le système de mémoire non volatile comprend une unité de commande (14) permettant de décaler des informations sectorielles vers un premier (210) et un second blocs (216) d'un super bloc particulier (204), et d'écrire des informations sectorielles sur le premier bloc (210) dudit super bloc, le décalage du second bloc (216) s'effectuant complètement pendant l'écriture sur le premier bloc, ce qui permet de réduire le temps nécessaire à l'exécution d'opérations d'écriture sur des blocs, et d'augmenter la performance globale du système.
