Abstract
A system and method are herein disclosed for managing memory defects in an information handling system. More particularly, a system and method are described for generating a usable memory map which excludes memory locations containing defect memory elements. In an information handling system, a memory defect map, which contains information about the location of defective memory elements, is coupled to the memory device. As a map of memory usable by the system is created, usable memory regions containing defective memory elements are excluded from the memory map. The memory map is passed to the operating system, which uses only those regions of memory designated as usable and non-defective.
