Write Data Mask
One write data mask (DM) pin for each 8 data bits (DQ) will be supported on DDR2 SDRAMs, Consistent with the
implementation on DDR-I SDRAMs. It has identical timings on write operations as the data bits, and though used in
a uni-directional manner, is internally loaded identically to data bits to insure matched system timing. DM is not used
during read cycles.
