Title (EN) OPTICAL MEMORY WITH STORAGE IN THREE DIMENSIONS
(FR) MEMOIRE OPTIQUE AVEC STOCKAGE TRIDIMENSIONNEL
Abstract:
(EN) A high storage capacity, fast access time, photovoltaic ferroelectric memory apparatus including a plurality of memory planes (1) which are stacked in a three dimensional configuration. Each plane is comprised of a photovoltaic ferroelectric layer (9) and a photoconductive layer (10) sandwiched between two electrodes (8), (11). Writing of information is effected by illuminating a selected xy location on the planes while simultaneously applying a voltage pulse to a selected z plane, and reading is effected by illuminating a selected xy location while connecting a selected z plane to a read amplifier.
(FR) Une memoire photovoltaique ferro-electrique a grande capacite de stockage et a acces rapide, comprend une pluralite de plans-memoires (1) empiles en une configuration tridimensionnelle. Chaque plan comprend une couche photovoltaique ferro-electrique (9) et une couche photoconductive (10) prises en en sandwich entre deux electrodes (8), (11). L"ecriture de l"information s"effectue par eclairage d"une adresse xy selectionnee sur les plans en appliquant simultanement une tension d"impulsion sur un plan z selectionne, la lecture s"effectuant par eclairage d"une adresse xy selectionnee tout en connectant un plan z selectionne a un amplificateur de lecture.
