This comment assumes that the leakage current is all of the power draw, and not just the majority of it. I find it unthinkable that leakage current is 99.99% of the power draw of SRAM. 95% sounds believable, but then you're talking about removing 500 mW, not 1 mW.

This also gets rather tricky, because the standard way to connect computer chips is with copper traces, which are wildly good conductors of heat. A solution like this will probably need optical interconnects with the made from a thermal insulator.

It's a fun design problem to chew on
