Abstract
a. Circuit de commande de mémoire. b. Circuit caractérisé par un générateur de signal de commande créant un signal de commande lorsque le contenu du moyen d'entrée de données reste inchangé dans une période prédéterminée et un circuit pour appliquer le signal de commande au moyen de commande d'adresse et au moyen de commande d'inscription pour inscrire le signal de sortie du moyen d'entrée de données à l'adresse choisie, dans la mémoire, lorsque le signal de commande du générateur de signal de commande est disponible, pour éviter toute détérioration de la mémoire.
