Abstract

La présente invention concerne un appareil pour l'extension de la capacité d'une mémoire en utilisant une logique associée aux modules de mémoire. La logique est prévue pour la sélection d'une ou plusieurs pages, chacune ayant en substance la même adresse qu'une autre. Le dispositif est prévu pour effectuer la sélection par l'utilisation d'une instruction spéciale, et inclut les moyens de décodage pour les bits spécialisés de l'instruction.
