http://www.selotips.com/cara-mengetahui-ram-pc-ddr-berapa/ WebThe Clock, Command & Address lines (A, CK, CKE, WE, CSn) on a DIMM are connected using a technique called fly-by routing topology. This is done because all DRAMs on the DIMM share the same address lines and fly-by routing is required to achieve better signal integrity and the high speeds. Figure 11: Example System in Detail
