Figure19 : Read to Precharge (BL=4)
Figure18 : Read to write terminate (BL=4 or 8)
Notes:
1. Dout n = Data-Out from Column n , Din m = Data-In from Column m.
2. CKE=high
3. Shown with nominal tAC, tDQSCK and tDQSQ
Notes:
1. Dout n = Data-Out from Column n.
2. Read to Precharge equals 2 tCK, which allows 2 data pairs of Data-Out.
