What is Z-Angle Memory and why is Intel developing it?

Where is the music video for us who only want to learn about low level hardware through that medium?

But will this go the way of a “non core” product like Optane (or modems for that matter?)

The article says nothing about the construction or special qualities of ZAM, as compared to HBM :(

It’s crazy that we have stalled on the structure of the basic DRAM cell for decades now.

I have a feeling this will go the way of Optane and once it becomes useful they'll pull it and shelve it while keeping the patents/license of course so no one else can improve on it

This wccf article also doesn't do a great job of describing, but the third slide it shows is very illustrative: rather than stack horizontally it stacks dram on its side. https://wccftech.com/intel-zam-memory-threatens-hbms-ai-thro...

I thought this was going to mean each stack was able to directly talk to the controller, since all stacks are resting on an interposer thing. But actually there is still a logic controller slice at the bottom of the stack, not at a right angle to the stack.

Instead of HBM microbumps between layers there is a more compact/dense TSV ("fusion bonded via-in-one") system. Intel once more showing their strong chiplet packing prowess! The claim is that thermals are still much better somehow, in spite of volumetric cell density increasing (from thinner layers). The demo has 8+1 dram+controller layers.

Intel does these "throw spaghetti on the wall" kind of investments into potientially interesting companies/technologies all of the time - and have done so for decades.

Every time the recipient hypes the shit out of it, of course.
