Abstract

L'invention concerne une méthode de fonctionnement d'un système de stockage à mémoire non volatile. Dans cette méthode, une commande d'écriture est reçue, afin d'écrire des données. On alloue à la commande d'écriture une période d'attente pour exécuter la commande d'écriture. Pendant ladite période d'attente, on effectue une partie de l'évacuation des déchets numériques. Les données associées à la commande d'écriture sont écrites dans un tampon associé au système de stockage à mémoire non volatile.
