SYSTEM AND METHOD FOR PROVIDING A HIGH FAULT TOLERANT MEMORY SYSTEM

摘要

A system and method for providing a high fault tolerant memory system. The system includes a memory system having a memory controller, a plurality of memory modules and a mechanism. The plurality of memory modules are in communication with the memory controller and with a plurality of memory devices. The plurality of memory devices include at least one spare memory device for providing memory device sparing capability. The mechanism is for detecting that one of the memory modules has failed possibly coincident with a memory device failure on an other of the memory modules. The mechanism allows the memory system to continue to run unimpaired in the presence of the memory module failure and the possible memory device failure.
