Abstract :
In this paper we showed the signal degradation parts in high-speed channel of FB-DiMM system. And we also showed possible countermeasure. For the verification propose and also for establishing the precise modeling and simulation method, we compared measurement and simulation up to 9.6Gbps operation with test board. And we get good relation between them. After getting the calculated loss budget of estimated system, we made recommendations of preferable changes to main board and DiMM socket.
