Abstract

L'invention concerne un procédé s'appliquant à la récupération progressive de l'espace mémoire et consistant à recevoir une commande d'écriture pour inscrire une écriture mémoire dans un métabloc, effectuer une première partie de l'opération de récupération de l'espace mémoire et stocker l'écriture mémoire dans une partie tampon du métabloc.
