Abstract

a. Microprocesseur comportant une RAM sur le même chip ainsi qu'un circuit pour relier la RAM au bus de données interne du microprocesseur ainsi qu'au bus externe de données. b. Microprocesseur caractérisé en ce qu'il comporte un amplificateur de détection ayant une sortie reliée à au moins un inverseur ainsi qu'un commutateur bilatéral branché entre l'inverseur et le bus de données de microprocesseur, ce commutateur assurant l'interconnexion entre la RAM et le bus de données du microprocesseur et le bus externe de données.
