Systems and methods are provided that provide protection from undesired latching that may be caused by indeterminate interamble periods in an input/output data strobe (DQS) signal. Interamble compensation circuitry selectively filters out interamble states of the DQS signal to reduce provision of interamble signals to downstream components that use the DQS signal to identify data latching times.
