| http://www.w3.org/ns/prov#value | - Although the measurement circuitry 30 shown in FIG. 4 can determine the DEL value corresponding to the timing of the DQS and DQS* signals relative to the DQ signal, it can be very difficult to determine the actual time corresponding to any delay value DEL. In particular, the delay provided by delay lines varies with such factors as process variations, junction temperature, and supply voltage.
