US09252997B1 Data link power reduction technique using bipolar pulse amplitude modulation
High-speed data links between a processor and off-chip DRAM utilizes pulse-amplitude-modulation (PAM) signaling to increase data rate for a given bandwidth and resource budget in SoCs. However, the termination resistor used in the transmission line interface between processor and DRAM consumes large amounts of power during PAM signaling.

Additionally, data inversion pre-coding may be concatenated with the floor voltage adjustment to further maximize power savings of the interface.
