ABSTRACT:
A method and system for enterprise memory management of memory modules of a computer system. The method includes scanning memory chips of a memory module for errors, analyzing a scrub error map corresponding to a scrubbing operation of the memory module, generating a scrub map summary based upon the scrub error map analyzed, creating an error history map by adding the scrub map summary generated, analyzing the error history map created and tracking a chip location for each memory chip of the memory module including errors, and determining a scrubbing algorithm of the memory module based on the analyzed error history map. The enterprise memory management system includes a plurality of computers each including memory modules, and an enterprise memory manager which collects and analyzes error history maps corresponding to each computer and determines a scrubbing algorithm of the memory modules of each computer.
