Microsoft patents system to track and repair faulty computer memory

Patent drawing
Patent drawing from the official filing.

Microsoft describes a method for computers to identify sections of memory that are failing and send a list of these errors to a cloud server for backup. The system also works with the computer's basic startup software to attempt repairs, then updates the error list based on what was fixed and what was saved in the cloud.

Why it mattersThis helps ensure that if a computer crashes or loses data, it can recover the correct list of faulty memory parts from the cloud to avoid using bad sectors again.

In the filing’s own words

Systems and methods are provided for implementing improved memory defect management. Bad pages, referring to portions of memory affected by memory errors, are identified by an operating system (“OS”) of a computing system. A list of bad pages may be periodically uploaded to a cloud data storage. The OS may also send the list of bad pages to a basic input/output system (“BIOS”) for repair of some of the bad pages. A list of repaired bad pages or corresponding status information may be sent to the OS. In some examples, the list of bad pages is compared with the list of repaired bad pages and may be updated accordingly. The list of bad pages may be compared with a previously uploaded list of bad pages that has been received from the cloud data storage. One list may be updated with, or replaced by, the other list based on the comparison.
