MREP training aligns the Read MDQS phase with the
data buffer clock. In this training mode the memory controller sends a sequence of read
commands, the DRAM sends out the MDQS, the data buffer samples the strobe with the clock
and feeds the result back on DQ. Calibration continues to perform this training to find
the 0 to 1 transition on the Read MDQS sampled with the data buffer clock.
