Title (EN) SPACE MANAGEMENT FOR MANAGING HIGH CAPACITY NONVOLATILE MEMORY
(FR) GESTION D'ESPACE POUR LA GESTION D'UNE MEMOIRE NON VOLATILE HAUTE CAPACITE
Abstract:
(EN) A controller device (10) includes a space manager circuit (28) responsive to address information from a host (22) and operative to read, write and erase information in a nonvolatile memory unit (16) based on the host address information. The space manager circuit (28) assigns a predetermined number of blocks (202, 204, 206, 208), in sequential order to each of the nonvolatile memory device, forms super block, each super block having blocks arranged in parallel, identifies a particular super block having at least two blocks, a first block being located in a first nonvolatile memory device and a second block being located in a second nonvolatile memory device, for erasure of the particular super block.
(FR) La présente invention concerne un dispositif de contrôle (10) comportant un circuit de gestion d'espace (28) sensible à une donnée d'adresse provenant d'un hôte (22) et opérant en lecture, en écriture et en effacement de donnée dans une unité de mémoire non volatile (16) sur la base de la donnée d'adresse du hôte. Le circuit de gestion d'espace (28) attribue un nombre prédéterminé de blocs (202, 204, 206, 208), en ordre de séquence à chaque dispositif de mémoire non volatile, constitue un super bloc, chaque super bloc présentant des blocs disposés en parallèle, identifie un super bloc spécifique ayant au moins deux blocs, un premier bloc étant situé dans un premier dispositif de mémoire non volatile et un deuxième bloc étant situé dans un deuxième dispositif de mémoire non volatile, pour l'effacement de ce super bloc spécifique.
