Zusammenfassung:A system and method for storing error correction check words in computer memory modules. Check bits stored in physically adjacent locations within 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 errors in two or more check bits stored in physically adjacent memory locations will appear as single-bit errors to an error correction subsystem. Similarly, the likelihood of multi-bit errors occurring in the same check word may be reduced.
