NOP commands are shown for ease of illustration; other commands may be valid at these times. 2. t WTR controls the WRITE-to-READ delay to the same device and starts with the first rising clock edge after the last write data shown at T9. 3. The BL8 setting is activated by either MR0[1:0] = 00 or MR0[1:0] = 01 and MR0[12] = 1 during the WRITE command at T0. The READ command at Ta0 can be either BC4 or BL8, depending on MR0[1:0] and the A12 status at Ta0. 4. DI n = data-in for column n. 5. RL = 5 (AL = 0, CL = 5), WL = 5 (AL = 0, CWL = 5). 2Gb: x4, x8, x16 DDR3 SDRAM WRITE Operation
