Abstract
A method and device for error detection includes performing error detection for each data word received in a burst access to a memory. When no error is detected, the data words are written to a cache and indicated as valid data. In response to detecting an error in a data word, the error is corrected and the corrected data written to the cache without indicating the data as valid. In addition, the location of the detected error, indicating the data symbol associated with the error, is recorded in an error vector. The error vectors associated with each data word in the burst access are compared to determine whether a detected error was properly corrected.
