Abstract
Operating a DDR4 memory channel at speeds of only 2666MT/s can be a challenge for multi-slot setups. So what will be required in the next-generation DDR5 memory busses to enable them to run at speeds of 3200MT/s and above? What are the implications for controllers, and how does one plan the supported topologies for a given controller?
