Abstract

L'invention concerne un procédé de mémorisation de données permettant des détections et corrections d'erreur dans une mémoire organisée pour lire et écrire des mots d'un premier nombre (m) de bits et éventuellement pour modifier une partie seulement d'un tel mot, comprenant les étapes suivantes associer un code de détection et de correction d'erreur à un groupe d'un deuxième nombre (k≥) de mots ; et à chaque écriture partielle dans le groupe de mots calculer un nouveau code du groupe de mots modifié, effectuer une opération de vérification et, si une erreur apparaît, effectuer une correction d'erreur du mot modifié et/ou du nouveau code.
