ABSTRACT:
An embodiment may be an apparatus comprising a link coupled with a memory, and circuitry coupled with the link to calculate the amount of memory access idle time, determine if memory access idle time is sufficient to change to a self-refresh state, and change to a self-refresh state based on memory access idle time without explicit notification from a processor regarding the processor power state. Another embodiment may be a method for memory to enter self-refresh comprising calculating the amount of memory access idle time, determining if memory access idle time is sufficient to change to a self-refresh state, and changing to a self-refresh state based on memory access idle time without explicit notification from a processor regarding the processor power state. Various other embodiments systems, methods, machine readable mediums and apparatuses may provide similar functionality to these exemplary embodiments.
