GENERATION AND USE OF SYSTEM LEVEL DEFECT TABLES FOR MAIN MEMORY

摘要

Methods and apparatus for maintaining and utilizing system memory defect tables that store information identifying defective memory locations in memory modules. For some embodiments, the defect tables may be utilized to identify and re-map defective memory locations to non-defective replacement (spare) memory locations as an alternative to replacing an entire memory module. For some embodiments, some portion of the overall capacity of the memory module may be allocated for such replacement.
