WebAbstract: Impact of non-target ODT (On-Die Termination) in dual-rank DRAM is investigated on SoC-DRAM SI (signal integrity). Analysis at data rate of 4266Mbps was performed. It shows that terminating non-target DRAM improves SI of the target DRAM by ~3-5% of unit interval due to mitigation of reflections. WebThe intent of dynamic ODT is to allow the desired ODT value (larger R) to be opportun-istically applied during writes, while also allowing a different ODT value (smaller R) to be applied to the same memory when in standby and when a different rank is being written to in multirank systems. This requires the DRAM device to have its RTT_NOM bits
