GDDR3 SGRAM
Rev. 1.2
NOTE : 1. DO n (or b) = data-out from column n (or column b).
2. Burst length = 4
3. Three subsequent elements of data-out appear in the programmed order following DQ n.
4. Three subsequent elements of data-out appear in the programmed order following DQ b.
5. Shown with nominal tAC and tDQSQ.
6. Example applies when READ commands are issued to different devices or nonconsecutive READs.
7. RDQS will start driving high one half-clock cycle prior to the first falling edge of RDQS.
8. The minimum delay from a READ to a PRECHARGE command is BL/2.
