Specifically, the clocks, address, and control signals are all routed in a daisy-chained fashion, and termination is located at the end of each trace. 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.
