An Energy Efficient DDR5 I/O Performance Boost in Clamshell Configuration by Charge Pumping From Non-Target Device

This paper proposes a novel design technique to change non-target I/O load into a signal performance booster in dual-rank memory subsystem by recovering formerly wasted energy at the non-target device. This design technique is suitable for clamshell, dual-surface mounted DDR5 printed circuit board design, offering improved performance with a minimum power consumption.
