There's some hope of smaller SRAM in the future - https://raaam-tech.com/technology/ is a three-transistor SRAM.

It's not quite SRAM, it needs to be refreshed like DRAM. That's the main downside compared to SRAM but it's still very interesting.

Yes, the density vs power tradeoff could make a lot of sense in a few applications.

I wonder if it would start to make sense for SRAM caches to shrink (or not grow as fast) in favor of adding on chip DRAM cache at some tier.

		Or AMD’s putting sram on a separate chip. I’m surprised they didn’t go there yet except for extra L3 instead of all of it. At some point the costs will shift the decisions.
