Input slew rate is 1 V/ns and AC timings are guaranteed for linear signal transitions.
The CK/CK# input reference level (for timing reference to CK/CK#) is the point at which CK and CK# cross the DQS/DQS# input reference level is the cross point
when in differential strobe mode; the input reference level for signals other than CK/CK#, or DQS/DQS# is VREF.
