1. A method comprising:

  • engaging a normalizer circuit on a data strobe line that is not optimally terminated, the data strobe line having a preamble that precedes an initial valid edge, the data strobe line to provide a burst of sampling edges for sampling a data line, where a timing of the initial valid edge can drift within a tolerance, the normalizer circuit to drive the data strobe line toward a rail voltage;

    detecting an initial edge after engaging the normalizer circuit;

    generating a count triggered from the initial edge; and

    monitoring the count to identify the initial valid edge of the burst of sampling edges on the data strobe line and reject false sampling caused by noise on the data strobe line.
