Title
(EN) MEMORY DEVICE HAVING REDUNDANT MEDIA MANAGEMENT CAPABILITIES
(FR) DISPOSITIF DE MÉMOIRE AYANT DES CAPACITÉS DE GESTION DE SUPPORT REDONDANTES
Abstract
(EN)
Methods, systems, and apparatuses related to multiple instructions sets or redundant instructions for memory access and management. In one approach, a controller of the memory device provides a first set of functions for management of a storage media of the memory device. The controller uses the first set of functions to service one or more requests received from the host device. The controller provides a second set of functions for management of the storage media. The second set includes one or more functions that are redundant to the first set. When a request is received from the host device, in response to determining that the first set of functions is unavailable to service the request, the controller services the request using one or more of the redundant functions of the second set.
(FR)
L'invention concerne des procédés, des systèmes et des appareils associés à de multiples ensembles d'instructions ou à des instructions redondantes pour l'accès et la gestion de mémoire. Dans une approche, un contrôleur du dispositif de mémoire fournit un premier ensemble de fonctions pour la gestion d'un support de stockage du dispositif de mémoire. Le contrôleur utilise le premier ensemble de fonctions pour desservir une ou plusieurs demandes reçues du dispositif hôte. Le contrôleur fournit un deuxième ensemble de fonctions pour la gestion du support de stockage. Le deuxième ensemble comprend une ou plusieurs fonctions qui sont redondantes par rapport au premier ensemble. Lorsqu'une demande est reçue du dispositif hôte, en réponse à la détermination que le premier ensemble de fonctions est indisponible pour desservir la demande, le contrôleur dessert la demande en utilisant une ou plusieurs des fonctions redondantes du deuxième ensemble.
