Abstract
Disclosed embodiments include systems and methods for tracking defective memory using a shared memory defect list. Embodiments include firmware that identifies a memory buffer to store a list that includes an entry identifying a portion of memory as defective. The firmware sends an identification of the memory buffer to an operating system. The operating system reads the list from the memory and identifies the portion of defective memory based on the list. The operating system further manages memory locations used based on the identified portion of defective memory and avoids using the portion of defective memory. The firmware persists the contents of the memory to a non-volatile storage prior to shutting down the computer system.
