Scientists build a memory chip that breaks the rules of miniaturization

Thank you, got it now :-)

Interesting.

A switchable ferroelectric field in a remarkably small confined volume. Lots of fascinating engineering in turning that into a mass market product.

Is it "spintronics" again? It's been some years since spintronics were going to re-set the world.

One wonders that "reversible computing" was supposed to result the "ultra-efficient" systems. Then the "free-form 3-D IC" is supposed to be coming along, and entirely change the account of planar systolic design.

Also "holographic storage", wasn't that supposed to approach the theoretical information density?

Read the paper. Ferroelectric effects don't have anything to do with spintronics.

It's a much slower and coarser effect. Actual bits of matter (admittedly very small bits) move around and stay where they have been put.

Rather like writing, where lumps of pigment get deposited on paper, but on a much smaller scale

Do stop rabitting on about stuff you don't remotely understand.

Why would you think that? Holograms have to interact with photons, and optical photons are quite bulky.

ASML's lithography machine goes to a great deal of trouble to get 13.5 nanometre photons from droplets of very hot tin. Hard UV photons are below 200 nanometres.

As CMOS losses are mostly due to x-conduction and capacitive discharge, size reduction always tended to reduce per-cell losses.

Agreeably I don't know a very great much about electrical/computer engineering or design.

The ideas of theoretical limits after definitions of energy and information about "computronium" and then "memoronium" I suppose has that various accounts of reversible computing and holographic storage also reduce the cost of maintenance (of the routine) to zero, or as rather it "goes" to zero.

Then an idea of holographic storage is that addressing is geometric, meaning that there's an abstract sphere or other volumetric solid the outside of which any point of which and any direction futhermore results a different projection, much like how a phonographic record or compact disc the usual "platter" has that the read-head goes from outside to inside or inside to outside respectively, the idea of 3-D storage then that any great circle results a different access-patternry.

The reversible computing though is a pretty great idea that it's of a resonant circuit vis-a-vis the "burning the bits" and entropy that just shuffling the bits around as for accounts of gates of valves, results much less current to run the routine.

The rules of the model of computation, ....

Thanks for writing
