  • Patent number: 7823045
    Abstract: An error correction device includes a decoding unit, an error buffer, an error classifying unit and an error correction unit. The decoding unit reads data from a main memory and performs error detection on the data to generate error values and error addresses. Then, the error buffer temporarily stores the error values and the error addresses. The error classifying unit classifies the error addresses stored in the error buffer into a plurality of subclasses, where error values and error addresses which correspond to the same row of the main memory are classified into the same subclass. Finally, the error correction unit performs an error correction on the data stored in the main memory according to the plurality of subclasses. The error correction device therefore can reduce the amount of the change-row operations of the main memory so that the memory efficiency is increased.
