Hi, everyone I am designing a FPGA PCB board with one DDR2 dimm memory slot. As current project will only need single dimm slot, is that mean I don't need any termination resistor on the board? Since the DDR2 will have ODT(On Die Termination) technology. Even without ODT, it should not cause signal reflection problem since this is only one dimm slot. There is no standby hi-Z on the end of transmission line. So there is no necessary to put termination resistors on the end? Normal ref design have two DDR2 Dimm Slots, I believe single slot is different. Can anyone tell this idea is correct or more things need to be concern?
