12 years agoDDR3 dual-rank dual-slot pin assignment
Hello,
I cannot figure out how to assign CS#, ODT and CKE pins in DDR3 dual-rank dual-slot configuration. I'm using Micron 8GB part - MT16JTF1G64HZ. It has two ranks and two slots, selected by S0# and S1# pins. Also, it has two bits of ODT and CKE. Megawizard generates 4-bit CS#, ODT and CKE busses for 2-slot and 2-rank configuration. No S0 or S1. I haven't found any documentation on how to connect those bits to the IOs. It seems to require some additional muxing logic to interface with the DIMM on board. Thanks, EvgeniNo RepliesBe the first to reply
