	Since high-speed signals of 7 GHz or faster are transmitted along the PCB lines where the memory is connected, signal strength loss occurs due to signal reflection and coupling. Since the 0.1 mm thick lines are closely spaced at 0.2 mm intervals, they can interfere with each other and cause crosstalk. Therefore, it is necessary to analyze the characteristics of the high-speed signal lines on the PCB drawing in advance before printing the PCB. For DRAM mounted on the PCB, DIMM performance can have a great impact. Also, DDR channels are vulnerable to ISI (intersymbol innterference) effects.
