Summary: | Embodiments include a system, a memory controller, an apparatus, a device, and a method. An embodiment provides a device that includes a memory that requires a periodic refresh and having a nominal refresh period, and a processor operably coupled with the memory. The device also includes a hardware-implemented control circuit for periodically discovering a retention time of at least a portion of the memory that requires a periodic refresh. The hardware-implemented control circuit is also for determining a refresh period that is not more than the discovered retention time of the at least a portion of the memory that requires a periodic refresh, and for scheduling a refresh of the at least a portion of the memory that requires a periodic refresh at least once each refresh period. |
