Abstract

PROCEDE DE MISE EN MEMOIRE A ACCES DIRECT, STATIQUE ET NON-EVANESCENTE, ET DISPOSITIF DE MEMOIRE CORRESPONDANT. IL EST CONSTITUE PAR UNE CELLULE DE MEMOIRE A ACCES DIRECT 12 ET PAR UN ELEMENT DE MEMOIRE NON EVANESCENT 14 QUI PEUT ETRE RELIE A LA CELLULE 12 PAR COUPLAGE CAPACITIF, DE SORTE QUE LE CONTENU DE LA CELLULE 12 PEUT ETRE DIRECTEMENT REPRODUIT DANS L'ELEMENT 14 ET QUE LE CONTENU DE CET ELEMENT PEUT ETRE RETRANSCRIT DANS LA CELLULE 12 QUAND CELLE-CI EST REMISE SOUS TENSION APRES COUPURE DE L'ALIMENTATION. L'ELEMENT NON EVANESCENT PEUT ETRE UNE CELLULE A GRILLE FLOTTANTE A COUPLAGE AVEC LE SUBSTRAT, A EFFET AUTO-REGULATEUR ET A COURANT D'EFFET TUNNEL RENFORCE PAR DES ASPERITES.
