alt Hacker NewsNot to ruin a joke, but does it actually make a difference for SRAM? It’s two inverters in a loop, despite not being the same size they are active components. But I’m also a software guy so I could be totally wrong.

I have no idea in practice. But for the thermodynamic limit of actually making a difference, any irreversible change requires heat to be generated, e.g. initializing to zero, truncating, or bitshifts with discarded information. In contrast, addition/subtraction/multiplication/bitshifts without over-/under- flow will not necessarily generate heat.

PS. you can also use mass-energy equivalence to extend this to calculate the lower limit of mass for a given quantity of information. TL;DR: The internet weighs 50g https://www.youtube.com/watch?v=WaUzu-iksi8
I think displaying black or white pixels makes a bigger difference.
