Notes:
Figure 85 (page 166) shows the strobe to clock timing during a WRITE. DQS, DQS# must
transition within 0.25
mask setup and hold timings are measured relative to the DQS, DQS# crossing, not the
clock crossing.
The WRITE preamble and postamble are also shown here. One clock prior to data input
to the DRAM, DQS must be HIGH and DQS# must be LOW. Then for a half clock, DQS is
driven LOW (DQS# is driven HIGH) during the WRITE preamble,
must be kept LOW by the controller after the last data is written to the DRAM during the
WRITE postamble,
Data setup and hold times are shown. All setup and hold times are measured from the
crossing points of DQS and DQS#. These setup and hold values pertain to data input
and data mask input.
Additionally, the half period of the data input strobe is specified by
