Le système de mémoire peut déterminer s'il faut ajouter des données reçues au tampon de suppression dynamique, au tampon temporaire ou à une combinaison desdits tampons en fonction d'une taille de transfert de données et d'une taille seuil. Si les données dans le tampon temporaire répondent à une condition de copie, les données dans le tampon temporaire sont copiées dans le tampon de suppression dynamique. Si les données dans le tampon de suppression dynamique répondent à une condition de suppression dynamique, les données dans le tampon de suppression dynamique sont écrites dans le dispositif de mémoire à partir d'un décalage de page multi-plan de zéro.
