摘要: A system and method for storing error correction check words in computer memory modules. Check bits stored within a given word line in a dynamic random access memory (DRAM) chip are assigned to different check words. By assigning check bits to check words in this manner, multi-bit soft errors resulting from the failure of a word line will appear as single-bit errors to an error correction subsystem.
