DQS
I/O
Data Strobe: Output with read data, input with write data. DQS is
edge-aligned with read data, centered in write data. It is used to
capture data. For the x16 , LDQS is DQS for DQ0-DQ7 and UDQS is
DQS for DQ8-DQ15. Pin 16 is NC on x4 and x8.
DQ Power Supply: +2.5V ±0.2V. Isolated on the die for improved
noise immunity.
DQ Ground. Isolated on the die for improved noise immunity.
Power Supply: +2.5V ±0.2V.
Ground.
SSTL_2 reference voltage.
No Connect: These pins should be left unconnected.
