I think that one of the NVRAM solutions in development like Intel and Micron's 3D xpoint might have lower power consumption per GB than DRAM given the non-volatility and thus the obviated need to continually refresh the value. So if we were to see DRAM replaced by NVRAM (or at least augmented, where all but the most critical data were shuffled from DRAM -> NVRAM each time the screen locked), that might be a pathway.

I tried to find some numbers on this, but this is outside of my area of expertise. Would love to hear somebody more knowledgable weigh in.
