Data Strobe: Output with read data, input with write data. Edge-aligned with read data, cen-
tered in write data. For the x16, DQSL: corresponds to the data on DQL0-DQL7; DQSU corre-
sponds to the data on DQU0-DQU7. The data strobe DQS, DQSL and DQSU are paired with
I/O
differential signals DQS, DQSL and DQSU, respectively, to provide differential pair signaling
to the system during reads and writes. DDR3 SDRAM supports differential data strobe only
and does not support single-ended.

Input Data Mask: DM is an input mask signal for write data. Input data is masked when DM
is sampled HIGH coincident with that input data during a Write access. DM is sampled on
I
both edges of DQS. For x8 device, the function of DM or TDQS/ TDQS is enabled by Mode
Register A11 setting in MR1.
