Title (EN) SYSTEM FOR BLOCK RELINKING
(FR) SYSTÈME DE RÉASSOCIATION DE BLOCS
Abstract:
(EN) In accordance with various embodiments of the present invention, a system for block relinking during garbage collection is described. The system may include a non-volatile memory storage system including a memory configured to store a storage system firmware, a non-volatile memory cell array configured to maintain a first metablock, the first metablock comprising a block of the first metablock, and a processor in communication with the memory and the non-volatile memory cell array, the processor being configured to execute the storage system firmware stored in the memory, the storage system firmware comprising program instructions for writing a memory write to update a block of a first metablock to a block of a second metablock, copying valid portions of the block of the first metablock to the block of the second metablock, and linking the block of the second metablock to the first metablock.
(FR) Cette invention concerne un système de réassociation de blocs au cours d'une récupération de l'espace mémoire. Le système peut comprendre un système de stockage de mémoire non volatile comprenant une mémoire configurée pour stocker un micrologiciel du système mémoire, une matrice de cellules de mémoire non volatile configurée pour maintenir un premier métabloc, ce premier métabloc comprenant un bloc du premier métabloc, et un processeur communiquant avec la mémoire et la matrice de cellules de la mémoire non volatile, le processeur étant configuré pour exécuter le micrologiciel du système mémoire stocké dans la mémoire, le micrologiciel du système mémoire comprenant des instructions de programme pour enregistrer une écriture afin d'actualiser un bloc d'un premier métabloc dans un bloc d'un second métabloc, copier des parties valides du bloc du premier métabloc sur le bloc du second métabloc et associer le bloc du second métabloc au premier métabloc.
