Abstract

Une mémoire matricielle comprend un réseau 10 d'éléments de stockage à semi-conducteurs à seuil modifiable 10.10 à 10.32 dont chacun ne comporte qu'une source et une grille, et dont chacun sert, en cours de fonctionnement, de condensateur modifiable pouvant être positionné sélectivement dans un premier ou un second état. Des dispositifs de lecture 12, 18 sont prévus pour appliquer un signal de lecture à la grille d'un élément de stockage sélectionné, et la disposition est telle qu'un signal de tension est ainsi généré à la source de l'élément selectionné, ce signal étant appliqué à une entrée d'un amplificateur de détection 30 qui est disposé pour comparer ce signal à une tension de référence appliquée à une seconde entrée de l'amplificateur et, à la suite de cette comparaison, pour produire un signal de sortie indiquant l'état de l'élément de stockage sélectionné. Une densité d'enregistrement élevée peut être obtenue avec cette mémoire, car aucune connexion de drain aux éléments de stockage n'est nécessaire, et parce que la fonction de lecture est très fiable.
