Title (EN) METHOD OF ERROR CORRECTION IN A FLASH MEMORY
(FR) PROCÉDÉ DE CORRECTION D'ERREUR DANS UNE MÉMOIRE FLASH
Abstract:
(EN) The present invention relates to a method of error correction in a nonvolatile flash memory of NAND type, said memory comprising a first and a second identical copies (SW1, SW2) of an item of software to be loaded, a page (P1) of a block (B2) occupied by data of the first copy (SW1) of the item of software being corrupted, and a page (P3) of a block (B53) occupied by data of the second copy (SW2) of the item of software being corrupted, said method comprising: the replacement of the block occupied by the second copy of the item of software and comprising a corrupted page by the identical block occupied by the first copy of the item of software, making it possible to correct the second copy of the item of software; the re-execution of the booting loading program; the loading of the second copy of the item of software.
(FR) La présente invention concerne un procédé de correction d'erreur dans une mémoire flash non volatile de type NAND, ladite mémoire comprenant une première et une deuxième copies (SW1, SW2), identiques, d'un logiciel à charger, une page (P1) d'un bloc (B2) occupé par des données de la première copie (SW1) du logiciel étant corrompue, et une page (P3) d'un bloc (B53) occupé par des données de la deuxième copie (SW2) du logiciel étant corrompue, ledit procédé comprenant : le remplacement du bloc occupé par la deuxième copie du logiciel et comprenant une page corrompue par le bloc identique occupé par la première copie du logiciel, permettant de corriger la deuxième copie du logiciel; la réexécution du programme de chargement au démarrage; le chargement de la deuxième copie du logiciel.
