Abstract
A method and apparatus are provided for capturing data read from a memory device that is aligned with respect to a clock strobe signal originating from the memory device, which has constraints with respect to a local clock signal supplied to the memory device. The apparatus includes a circuit for capturing the data read from the memory device relative to the clock strobe signal to produce captured read data, a circuit for latching the captured read data relative to a sample clock signal, and a circuit for measuring a phase difference between the sample clock signal and the clock strobe signal and adjusting a phase of the sample clock signal as a function of the phase difference.
