Title (EN) RANDOM ACCESS MEMORY POWER SAVINGS
(FR) ÉCONOMIES D'ÉNERGIE DE MÉMOIRE VIVE
Abstract:
(EN) Devices and techniques for random access memory power savings are disclosed herein. Data contained in RAM is compressed in response to obtaining a trigger. Here, the RAM organized into several discrete hardware components with a corresponding power control. The data contained in the RAM is replaced with the compressed data to free a discrete hardware component of the RAM. The discrete hardware component is then powered down via the corresponding power control.
(FR) L'invention concerne des dispositifs et des techniques pour des économies d'énergie de mémoire vive. Les données contenues dans la RAM sont compressées en réponse à l'obtention d'un déclencheur. Ici, la RAM est organisée en plusieurs composants matériels discrets avec une commande de puissance correspondante. Les données contenues dans la RAM sont remplacées par les données compressées afin de libérer un composant matériel discret de la RAM. Le composant matériel discret est ensuite mis hors tension par l'intermédiaire de la commande de puissance correspondante.
