Semron bas\u00e9e \u00e0 Dresde en Allemagne a lev\u00e9 7,3 millions d’euros pour le traitement de l’intelligence artificielle bas\u00e9 sur des dispositifs m\u00e9moire \u00e0 condensateurs.<\/span><\/h3>\n

Le tour de table a \u00e9t\u00e9 men\u00e9 par Join Capital et soutenu par SquareOne, OTB Ventures et Onsight Ventures.<\/p>\n

L’entreprise affirme que l’utilisation d’un dispositif inhabituel appel\u00e9 memcapacitor par analogie \u00e0 memristor – pourrait permettre une augmentation spectaculaire de la densit\u00e9 de traitement ainsi qu’une r\u00e9duction de la consommation d’\u00e9nergie pour les op\u00e9rations math\u00e9matiques de base qui sont au c\u0153ur de l’intelligence artificielle.<\/p>\n

La technologie a \u00e9t\u00e9 \u00e9tudi\u00e9e par les fondateurs, le PDG Aron Kirschen et le directeur technique Kai Uwe Demasius, pendant leurs \u00e9tudes \u00e0 l’Universit\u00e9 technique de Dresde pour le premier et \u00e0 l’Institut Max Planck de technologie pour le second.. Stuart Parkin, directeur g\u00e9n\u00e9ral de l’Institut Max Planck de physique des microstructures, qui a travaill\u00e9 37 ans chez IBM et qui a \u00e9t\u00e9 membre de l’IBM Fellow, est l’un des coauteurs de l’article.<\/p>\n

Les memcondensateurs de Semron sont fabriqu\u00e9s \u00e0 partir de mat\u00e9riaux semiconducteurs conventionnels d\u00e9pos\u00e9s sur des plaques de silicium sur isolant (SOI). Ils fonctionnent en exploitant le blindage des charges. Les memcondensateurs contr\u00f4lent un champ \u00e9lectrique entre une \u00e9lectrode sup\u00e9rieure et une \u00e9lectrode inf\u00e9rieure par l’interm\u00e9diaire d’une \u00ab\u00a0couche de blindage\u00a0\u00bb.<\/p>\n

La CapRAM est constitu\u00e9e de r\u00e9seaux planaires de condensateurs m\u00e9moires qui peuvent \u00e9galement \u00eatre empil\u00e9s dans la troisi\u00e8me dimension. Cela permet d’obtenir une densit\u00e9 de traitement extr\u00eame. Semron envisage d’empiler jusqu’\u00e0 100 couches d’une mani\u00e8re similaire aux m\u00e9moires flash 3D-NAND.<\/p>\n

Pour rester compacte tout en g\u00e9n\u00e9rant un minimum de chaleur, l’architecture utilise un syst\u00e8me de calcul analogique en m\u00e9moire \u00e9quivalent \u00e0 plusieurs bits. La CapRAM stocke \u00e9galement les charges pour la multiplication de la matrice en tant que capacit\u00e9 variable.<\/p>\n

La soci\u00e9t\u00e9 affirme que la CapRAM offre un avantage fondamental, car elle est dot\u00e9e d’une lecture capacitive, le bruit est plus faible que dans toutes les autres technologies. \u00ab\u00a0Peu importe que l’on utilise des m\u00e9moires SRAM, des m\u00e9moires \u00e9mergentes telles que les m\u00e9moires \u00e0 changement de phase (PCM) ou d’autres technologies r\u00e9sistives, elles n’atteindront jamais l’efficacit\u00e9 \u00e9nerg\u00e9tique de la CapRAM, et donc la densit\u00e9 de l’intelligence\u00a0\u00bb, affirme l’entreprise sur son site web.<\/p>\n
