Abstract
SYSTEME DE CONSERVATION ET DE VERIFICATION DE MEMOIRE, A DEUX SOURCES D'ALIMENTATION ET COMMUTATION POUR PASSER D'UNE SOURCE A L'AUTRE EN CAS DE DEFAILLANCE D'UNE SOURCE AFIN D'EVITER LA DESTRUCTION DES DONNEES DE LA MEMOIRE. UNE SOURCE PRINCIPALE DE COURANT 20 ET UNE SOURCE AUXILIAIRE DE COURANT 22 ALIMENTENT A TRAVERS UN COMMUTATEUR 24 LA MEMOIRE 12 DONT ON VEUT CONSERVER ET VERIFIER LES DONNEES; LA SOURCE AUXILIAIRE 22 EST RELIEE PAR LE COMMUTATEUR 24 A LA MEMOIRE EN CAS D'INTERRUPTION OU DE PERTE DE L'ALIMENTATION PAR LA SOURCE PRINCIPALE 20, OU INVERSEMENT; UN GENERATEUR 30 FOURNIT UN PREMIER NOMBRE ET UN CIRCUIT DE LOGIQUE DE TRAITEMENT ET DE COMMANDE 18 FOURNIT UN SECOND NOMBRE, CES NOMBRES ETANT EMMAGASINES A DES EMPLACEMENTS CHOISIS ET VOISINS DE LA MEMOIRE, PUIS RECHERCHES POUR VERIFIER LEUR RELATION MATHEMATIQUE QUI INDIQUE L'ETAT DE LA MEMOIRE. APPLICATION A TOUS APPAREILS ELECTRIQUES COMPRENANT DES CIRCUITS DE TRAITEMENT NUMERIQUE.
