Title
(EN) MEMORY DEVICE REFRESH COMMANDS ON THE FLY
(FR) COMMANDES D'ACTUALISATION À LA VOLÉE DE DISPOSITIFS MÉMOIRE
Abstract
(EN)
On the fly switching from one memory device refresh rate to another is provided. Control logic associated with the memory device detects a condition to switch from a currently-applied refresh rate to a different refresh rate. In response to the condition, the refresh rate is dynamically switched. The switching does not require a change of a mode register. Thus, a refresh rate for the memory device can be dynamically changed on the fly.
(FR)
L'invention concerne une commutation à la volée depuis un taux d'actualisation de dispositif mémoire vers un autre. Une logique de commande associée au dispositif mémoire détecte une condition de commutation depuis un taux d'actualisation actuellement appliqué vers un taux d'actualisation différent. En réponse à la condition, le taux d'actualisation est commuté de façon dynamique. La commutation ne requiert pas de modification de registre de mode. Un taux d'actualisation pour le dispositif mémoire peut donc être modifié de façon dynamique à la volée.
