SOLID STATE DRIVE WITH SELF-REFRESH POWER-SAVING MODE

A storage device (28) includes a non-volatile memory (32), a volatile memory (40) and a controller (36). The volatile memory supports a normal mode and a self-refresh mode. The controller is configured to store data for a host (24) in the non-volatile memory while using the volatile memory in the no...

Zusammenfassung:A storage device (28) includes a non-volatile memory (32), a volatile memory (40) and a controller (36). The volatile memory supports a normal mode and a self-refresh mode. The controller is configured to store data for a host (24) in the non-volatile memory while using the volatile memory in the normal mode and, in response to receiving a power-down command from the host, to deactivate at least part of the storage device and to switch the volatile memory from the normal mode to the self-refresh mode. Dans cette invention, un dispositif de mémorisation (28) comprend une mémoire non volatile (32), une mémoire volatile (40) et un contrôleur (36). La mémoire volatile peut fonctionner en mode normal et en mode rafraîchissement automatique. Le contrôleur est conçu pour placer des données destinées à un hôte (24) dans la mémoire non volatile pendant que la mémoire volatile est en mode normal, et, en réponse à la réception d'un ordre de mise hors tension en provenance de l'hôte, désactiver au moins une partie du dispositif de mémorisation et faire passer la mémoire volatile du mode normal au mode rafraîchissement automatique.
