Problems solved by technology

Thus, not only is system memory becoming a substantial portion of the overall solution cost over time, but the impact of erroneous behavior in memory can have an even more adverse effect on the associated replacement costs of the computing system

Abstract

A method for storing a memory defect map is disclosed whereby a memory component is tested for defects at the time of manufacture and any memory defects detected are stored in a memory defect map and used to optimize the system performance. The memory defect map is updated and the system's remapping resources optimized as new memory defects are detected during operation.

Description

technical field [0001] The present disclosure relates generally to computer systems and information processing systems, and more particularly to a system and method for creating a memory map used by a computer system or information processing system to manage its use. Background technique [0002] As the value and utility of information continue to increase, individuals and businesses are seeking alternative ways to process and store information. One option available to these users is information handling systems. Information handling systems generally process, aggregate, store and / or transmit information and data for business, personal or other purposes, thereby enabling users to exploit the value of the information. Due to the different technologies, information processing needs and requirements among different users or applications, the information processing system may be different in the type of information processed; the method of processing information; the method of...
