New Integrated 3D-Circuit Architecture With Spiraling Memory

[erek]

Impressed?

"Now, scientists from the Institute of Industrial Science at The University of Tokyo have developed a novel design for stacking resistive random-access memory modules with oxide semiconductor (IGZO) access transistor in a three-dimensional spiral. Having on-chip nonvolatile memory placed close to the processors makes the machine learning training process much faster and more energy-efficient. This is because electrical signals have a much shorter distance to travel compared with conventional computer hardware. Stacking multiple layers of circuits is a natural step, since training the algorithm often requires many operations to be run in parallel at the same time."

"even more energy efficient by implementing a system of binarized neural networks.
Instead of allowing parameters to be any number, they are restricted to either +1 or -1."
Any binarized neural network sounds like a case of majority voting logic to me.

IGZO is Indium Gallium Zinc Oxide. Transistors of this material are sometimes used in
display panels because its transparent. But in this case chosen for low off state leakage
to access a memresistor of some sort that wasn't specified.

If binary, that dumbs its function down the same as normal 1T1C DRAM. I don't see how
1T1R has any better use for AI. Unless its turning on several cells at the same time to take
a vote, or compare one population's vote vs another that sets the threshold. If the pops to
be compared organize as complete rows or colums, that might not be too difficult to wire.

Why would a memresistor with a binary state be better than capacitor with binary state?
Cause resistance isn't a charge that doesn't actively try to escape. Resistors might be
able to participate in parallel measurements that would merge and destroy individual
content stored in caps. Which is not to say you can't do this with caps, only that it is a
destructive process that may eat power and take time to write back.

Can't tell nothing for sure by these vague articles. Take none of this as actual information.
Entirely my guesswork at random in the dark. And what's the spiralled stacking all about?
-edit- Perhaps row vs row voting logic stacks and passes results to column vs column?
OOOOh, column in one layer vs row in another, store result back to either. Yeah, that...

Or we could put two fans with fins that don't align, and call it a co-processor on the back.

Fine. But when memory prices spiral out of control...

Whether one wants it or not ... you have no say so unless you go off the grid
