Data Strobe Bus

DQS0
I/O
SSTL
Data Strobe Bus 8:0
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 crosspoint 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.

Data Mask Signals

SSTL
Data Mask Bus 8:0
The data write masks, associated with one data byte. In Write mode, DM
operates as a byte mask by allowing input data to be written if it is LOW but
blocks the write operation if it is HIGH. In Read mode, DM lines have no effect.
