Abstract

L'invention concerne un montage intégré monolithique comportant des éléments de mémoire à un transistor. Ce dispositif comporte sur une couche isolante 11 recouvrant une couche semi-conductrice 1, un premier revêtement électriquement conducteur qui constitue une électrode de référence 10 commune aux condensateurs de mémoire Cl, C2 de tous les éléments de mémoire est placé à un potentiel de référence, et au-dessus du premier revêtement conducteur, en en étant séparé par une autre couche isolante 12, un second revêtement electriquement conducteur, qui constitue les électrodes 8, 9 des condensateurs de mémoire C1, C2, isolées les unes par rapport aux autres et chargées par les potentiels d'information devant être mémorisés. Application notamment aux mémoires dynamiques intégrées à semi-conducteurs.
