Abstract
A memory device providing signals indicating when refresh operations are complete. The signals from a number of memory devices can be combined, such as by logically ORing, to provide a refresh complete signal to a power management controller. Dynamic factors can affect the refresh operation and the memory may be refreshed without restoring the entire system to a high power state. The time required to perform a refresh operation can be determined dynamically, allowing the system to be returned to a low power state as soon as refresh is complete. Ambient temperatures can be monitored to dynamically determine when to perform a refresh operation.
