System Memory Interface 2.7 System Memory Layout Guidelines 2.7.1 System Memory Topologies (Min and Max Simulated Loading) Figure 2-8, Figure 2-9, Figure 2-10, and Figure 2-11 are the topologies that where simulated to develop the trace length recommendations in Section 2.7.2. These topologies are for reference only. Figure 2-8. CS, CKE, DQM, CLK, MA minimum loading topology CS, CKE, DQM, CLK, MA SDRAM Figure 2-9.
