Method and apparatus providing improved data path calibration for memory devices |
摘要 |
A method and apparatus for calibrating a data path of a digital circuit uses an even bit pseudo-random calibration pattern. A portion of the pattern is captured in a capture period and used to predict a next arriving portion of the calibration pattern. The next arriving portion of the calibration pattern is captured and then compared to the predicted pattern in a compare period, and the result of the comparison is used to relatively time data arriving in the data path to a clocking signal which clocks in the data. The time duration of the compare period may be varied to ensure that all possible bits of the calibration pattern are used in the calibration procedure.
