Input/Output
Input/Output
Data Input/Output: Lower byte of Bi-directional data bus.
Data Input/Output: Upper byte of Bi-directional data bus.
Lower byte data Strobe: Data Strobe output with read data, input with
write data of DQL[7:0]. Edge-aligned with read data, centered in write

data. DQSL is paired with DQSL# to provide differential pair signaling
to the system during read and write data transfer. DDR3 SDRAM
supports differential data strobe only and does not support single-
ended.
