Data Strobe Bus 7:0
The data strobes, associated with one data byte, sourced
with data transfers. In Write mode, the data strobe is
sourced by the controller and is centered in the data
window. In Read mode the data strobe is sourced by the
DDR2 SDRAM and is sent at the leading edge of the data
window. DQS signals are complements, and timing is
relative to the cross-point of respective DQS and DQS. If the
module is to be operated in single ended strobe mode, all
DQS signals must be tied on the system board to V_SS and
DDR2 SDRAM mode registers programmed appropriately.
