Abstract
A processing system employs techniques for enhancing dynamic random access memory (DRAM) page retirement to facilitate identification and retirement of pages affected by multi-page DRAM faults. In response to detecting an uncorrectable error at a first page of DRAM, the processing system identifies a second page of the DRAM for potential retirement based on one or more of physical proximity to the first page, inclusion in a range of addresses stored at a fault map that tracks addresses of DRAM pages having detected faults, and predicting a set of pages to check for faults based on misses at a translation lookaside buffer (TLB).
