Abstract:
A system and method for efficient data eye training reduces the time and resources spent calibrating one or more memory devices. A temporal calibration mechanism reduces the time and resources for calibration by reducing the number tests needed to sufficiently determine the boundaries of the data eye of the memory device. For one or more values of the voltage reference, the temporal calibration mechanism performs a minimal number of tests to find the edges of the data eye for the hold and setup times.
