Title (EN) METHOD TO WRITE IN A NON VOLATILE MEMORY AND SYSTEM TO IMPLEMENT SUCH METHOD
(FR) PROCEDE D'ECRITURE DANS UNE MEMOIRE NON VOLATILE ET SYSTEME PERMETTANT DE METTRE CE PROCEDE EN OEUVRE
Abstract: front page image
(EN)This invention concerns a method to write in a Flash type memory of an electronic module. The method consists in: associating at least two physical areas of said memory, called mirror areas, with the same logical area and during a write in said logical area, in programming the content of said logical area in one of said blank mirror areas; erasing the content of all mirror areas used in a single operation at a convenient time. This invention also concerns the smart card in which the method is implemented.
(FR)L'invention concerne un procédé permettant d'écrire dans une mémoire de type flash d'un module électronique. Ce procédé consiste à : associer au moins deux zones physiques de ladite mémoire, appelées zones miroir, à la même zone logique et, lors d'un processus d'écriture dans cette zone logique, programmer le contenu de ladite zone logique dans une desdites zones miroir vierges ; effacer le contenu de toutes les zones miroir utilisées au cours d'une opération unique, à un moment opportun. Cette invention concerne en outre une carte intelligence dans laquelle ledit procédé est mis en oeuvre.
