  DQS is a valid data signal. This is controlled by the MCB's hard core, and users do not need to care.

  DQS DQS_N is the interface between the controller and the DDR2 chip, and the user cannot control it. These two signals must be useful.

  DQS is the source synchronous clock. DQS is used to read the corresponding data DQ at the receiving end. Both the rising and falling edges are valid.
