1Gb DDR2 SDRAM
For proper operation of adjust mode, WL = RL - 1 = AL + CL -1 clocks and tDS / tDH should be met as the follow-
ing timing diagram. Input data pattern for adjustment, DT0 - DT3 is fixed and not affected by MRS addressing
mode (i.e. sequential or interleave). Burst length of 4 have to be programmed in the MRS for OCD impedance
adjustment.
Drive Mode
Drive mode, both Drive(1) and Drive(0), is used for controllers to measure DDR2 SDRAM Driver impedance
before OCD impedance adjustment. In this mode, all outputs are driven out tOIT after “enter drive mode” com-
mand and all output drivers are turned-off tOIT after “OCD calibration mode exit” command as the following timing
diagram.
