Abstract
L'invention concerne les cellules de mémoire. La cellule 10 se compose d'un circuit série comprenant le condensateur d'emmagasinage 14 et une impédance 16. Ce circuit est relié d'un côté à la masse et de l'autre à une ligne de bit/détection et comporte en outre un dispositif de couplage sélectif 12 commandé par une ligne de mot 22. Un amplificateur 20 amplifie le signal résultant de la charge contenue dans le condensateur 14. Applicable notamment dans la fabrication de mémoires d'ordinateurs.
