  • Replacement data error detector
    Patent number: 6868484
    Abstract: A cache includes an error circuit for detecting errors in the replacement data. If an error is detected, the cache may update the replacement data to eliminate the error. For example, a predetermined, fixed value may be used for the update of the replacement data. Each of the cache entries corresponding to the replacement data may be represented in the fixed value. In one embodiment, the error circuit may detect errors in the replacement data using only the replacement data (e.g. no parity or ECC information may be used). In this manner, errors may be detected even in the presence of multiple bit errors which may not be detectable using parity/ECC checking.
