Tracking address ranges for computer memory errors

摘要

Tracking address ranges for computer memory errors including detecting, by memory logic, an error at a memory address, the memory address representing one or more memory cells at a physical location of computer memory; reporting, by the memory logic to memory firmware, the detected error including providing the memory firmware with the memory address; identifying, by the memory firmware, an address range affected by the detected error including scanning the computer memory in dependence upon the memory address; determining, by the memory firmware, a region size based on the address range affected by the detected error; and populating an entry in a mark table corresponding to the detected error, including populating a field specifying the region size and a field specifying a match address corresponding to the memory address.
