Abstract

CIRCUIT ASSOCIE A UNE MEMOIRE MORTE PROGRAMMABLE EFFACABLE INTEGREE AVEC DES CIRCUITS UTILISANT UNE POLARISATION DE SUBSTRAT DE FACON A PRODUIRE LA TENSION DE LECTURE DE LA MEMOIRE APPROPRIEE INDEPENDAMMENT DE LA TENSION DE POLARISATION DU SUBSTRAT. CE CIRCUIT COMPREND UN GENERATEUR 40 DE TENSION DE REFERENCE QUI MESURE CONTINUELLEMENT LA TENSION DE SEUIL D'UN TRANSISTOR DE MEMOIRE A DEUX PORTES NON PROGRAMMEES 60, 62 ET PRODUIT UNE TENSION DE REFERENCE EXACTEMENT EGALE A CETTE TENSION DE SEUIL ET UN CIRCUIT 42 ELEVATEUR DE TENSION QUI ACCROIT LA TENSION DE REFERENCE D'UNE VALEUR FIXE POUR OBTENIR UNE TENSION DE PORTE OPTIMALE DES TRANSISTORS DE MEMOIRE 38 ET UN TEMPS D'ACCES DE LA MEMOIRE OPTIMAL. APPLICATION NOTAMMENT AUX MEMOIRES DE MICROPROCESSEURS INTEGREES SUR UNE UNIQUE MICROPLAQUETTE AVEC L'UNITE DE TRAITEMENT DU PROCESSEUR.
