DDR SDRAM technology has reached its 4th generation. The DDR4 SDRAM interface achieves a maximum data rate of 3.6Gbps per bit (i.e., clock rate of 1.8GHz). There are four key challenges in designing the placement and routing of DDR4 SDRAM interface with multi-Gigabit transmission. The major challenges include the routing topology and termination scheme for nets with multiple receivers, routing
