Abstract
A hierarchical error correction system and method operable with a computer memory system. In one embodiment, the memory system comprises a plurality of memory modules organized as a number of error correction code (ECC) domains, wherein each ECC domain includes a set of memory modules, each memory module comprising a plurality of memory devices. A first error correction engine is provided for correcting device-level errors associated with a specific memory device and a second error correction engine for correcting errors at a memory module level, wherein the first and second error correction engines are operable in association with a memory controller operably coupled to the plurality of memory modules.
