Abstract

In accordance with the present disclosure, a system and method are herein disclosed for managing memory defects in an information handling system. In an information handling system, a first quantity of memory, such as RAM, may contain defective memory elements. A second quantity of memory is physically coupled to the first quantity of memory and is used to store a memory defect map containing information regarding the location of defective memory elements in the first quantity of memory. The memory defect map may then be referenced by the BIOS or the operating system to preclude use of regions of memory containing defective memory elements.

Description

technical field [0001] The present invention relates generally to computing systems and information processing systems, and more particularly to a system and method for creating a memory map that manages its use with a computing system or an information processing system. Background technique [0002] As the value and use of information continue to grow, individuals and businesses are looking for more ways to process and store information. For these users, the information processing system is an optional path. An information handling system generally processes, compiles, stores, and / or transmits information or data for business, personal, or other purposes, thereby allowing users to exploit the value of the information. Since different users or different applications have different needs and requirements for technology and information processing, the information processing system may be different according to the type of information processed and the method of information p...
