Abstract
A method and circuit for generating a shifted strobe signal for sampling data read from a memory device includes generating an instantiation of a shifted strobe signal by applying both a coarse adjustment delay value and a fine adjustment delay value to a clock. Data read from a predetermined, programmed memory location or locations of the memory device is sampled using the shifted strobe signal. At least one of the applying steps is repeated and the read data is sampled again using the current instantiation of the shifted strobe signal. The process is repeated until the current instantiation of the shifted strobe signal is aligned with a valid data window of the memory device. The method can be used in both single data rate and double data rate applications.
