(EN) PARTITION PROTECTION METHOD AND APPARATUS FOR NON-VOLATILE MEMORY
(FR) PROCÉDÉ ET APPAREIL DE PROTECTION DE CLOISONNEMENT POUR MÉMOIRE NON VOLATILE
(ZH) 一种非易失性存储器的分区保护方法及装置
Abstract
(EN)
Disclosed are a partition protection method and apparatus for a non-volatile memory. The non-volatile memory comprises multiple storage partitions and a write protection bit storage area. The partition protection method comprises: performing first protection on a preset storage partition among multiple storage partitions on the basis of first protection information stored in the write protection bit storage area (S110); and performing second protection on the write protection bit storage area and/or the preset storage partition on the basis of preset second protection information (S120). Performing partition management on a non-volatile memory provides a more flexible and safer protection mechanism.

La présente invention concerne un procédé et un appareil de protection de cloisonnement pour une mémoire non volatile. La mémoire non volatile comprend une pluralité de cloisonnements de stockage et une zone de stockage de bits de protection contre l'écriture. Le procédé de protection de cloisonnement comprend les étapes suivantes : effectuer une première protection sur un cloisonnement de stockage prédéfini parmi une pluralité de cloisonnements de stockage sur la base de premières informations de protection stockées dans la zone de stockage de bits de protection contre l'écriture (S110) ; et effectuer une seconde protection sur la zone de stockage de bits de protection contre l'écriture et/ou le cloisonnement de stockage prédéfini sur la base de secondes informations de protection prédéfinies (S120). La gestion du cloisonnement sur une mémoire non volatile rend le mécanisme de protection plus flexible et plus sûr.
