Microsoft patents method to track memory health over time
Microsoft describes a system that saves data from when a computer's memory is first tested and compares it to later tests. By looking at how these numbers change, the system can tell if the memory component is starting to fail.
In the filing’s own words
The description relates to enhancing component and device reliability by analyzing stored margin data relating to the component. One example can obtain first margin data relating to a component from a first time and obtain second margin data relating to the component from a subsequent second time. The example can compare the first margin data to the second margin data to identify a change in a condition of the component.
What exactly they claim (claim 1)
1. A device, comprising: a memory unit; and, storage persistently storing first margin data from physical layer training of the memory unit at a first time and second margin data from physical layer training of the memory unit at a subsequent second time.
