Figure 47. Non-Gapless WRITEs
2.  WCK and CK are shown aligned (tWCK2CKPIN=0, tWCK2CK=0) for illustration purposes.  WCK2CK training determines the needed offset between WCK and CK.
4.  For WRITE operations it is important that the latching point meet the data valid window requirements, which may or may not be center aligned at the pins. 
5.  Before the WRITE commands, an ACTIVE (ACT) command is required to be issued to the GDDR5 SGRAM and tRCDWR must be met.

1.  WLmrs = 5 and tRCDWR = 3 is shown as an example.  Actual supported values will be found in the MR and AC timings sections.
3.  EDC may be on or off.  See Figure 4 for EDC Timing.
Notes:
6.  tWCK2DQI = 0 is shown for illustration purposes.
