To quote Newt from alien 2, "Ripley, it won't make a difference!" because SRAM is NOT scaling down!

> Beyond SRAM, the industry has been looking into many other alternative memory architectures. Emerging memory technologies include MRAM, FeRAM, NRAM, RRAM, STT-RAM, PCM, and others. Those emerging memory bitcells offer unique tradeoffs when compared to SRAM such as higher density at lower read/write specifications, non-volatility capabilities, lower read-write cycle capabilities, or lower power at potentially lower density or speeds. While they are not direct replacements for SRAM, moving forward they might play a role as level 4 or level 5 caches where the lower performance tradeoffs can be offset by higher density.
Besides the fact they will probably figure out a way to either replace sram with something else that does scale better or they will figure out novel techniques to scale sram.
