Dear All,


Hello. We found the 1st bit of the DQ amplitude was small by DDR3 stress test (Writing mode).

And, tDS/tDQ found tight specifications (DQS or DQ - CLK).

*Refer to attached file.


How to increase the DQ amplitude?

For example, if user increase the DQ Drive strength (40 Ohm --> 34Ohm), is this issue improved?
