Korean news are reporting this. Don't think it's made it to an English article yet: https://m.mt.co.kr/renew/view.html?no=2025011713082024514#_enliple
Tldr:
SK Hynix will begin mass production of its 10nm-class 6th generation (1c) DRAM in February 2025, marking another world-first milestone. The company previously developed the 16Gb DDR5 DRAM using the 1c process in August 2024.
According to industry reports, SK Hynix recently completed the Mass Production Qualification (MS Qual) for its 1c DDR5 DRAM, confirming consistent quality and yield across production batches. This certification signifies readiness for full-scale production.
This advancement strengthens SK Hynix's leadership in the next-generation memory market. DDR5 DRAM offers significant improvements in data transfer speed and power efficiency, meeting the demands of AI, big data, and cloud computing applications.

There are different gens in DDR5 RAM?
YairJ@reddit
This is referring to the microcircuits themselves. Different chips can be used to make a DDR5, etc card.
Frexxia@reddit
There are different nodes used for memory, just like for logic
Strazdas1@reddit
Also different nodes used for memory controllers that are often seperate than memory itself.

Why is it a milestone to produce memory in 10nm?
It is harder to shrink DRAM?
III-V@reddit
This is actually the 6th 10nm-class node I think. Iirc, there was 10x, 10y, 10z, 10a, and the current 10b.

Yea shrinking isn’t all good here. There are negative trade offs with a shrink

DRAM is essentially a capacitor bank to store bits. They scale fairly poorly.
You also have to be careful since modern DRAM gets attacked with memory access patterns that try to flip bits.
Automatic_Beyond2194@reddit
Yup. It’s generally not cost efficient with the diminishing returns.
And if anyone wants really high end memory they just get HBM

I can’t wait for a low power DDR6. Bandwidth in RAM is a pain right now and a 40% increase in bandwidth would really help the throughput. Could help a lot of next generation big APUs.

If LPDDR6 comes in CAMM as the form factor, and comes with true ECC as a requirement of the spec, I will be ecstatic. Doing all this, and managing to scale it well on a smaller node on top of that, would be the cherry on the cake.
DerpSenpai@reddit
We most likely will see LPDDR6 compatible chips coming out late this year with LPDDR6 products coming next year.

CAMM should help with latency too
StarbeamII@reddit
Will this overclock better than Hynix A-die? With DDR4 Samsung B-die overclocks a lot better than subsequent node-shrunk Samsung DDR4 chips
Noreng@reddit
Most likely not, as DRAM cells get smaller their tolerances get tighter. This has been the case for DDR, DDR2, DDR3, and DDR4
dracon_reddit@reddit
Which RAM chips will OC well is known to be more or less a complete crapshoot. They’re not engineered for it and so there’s no telling until they hit the market.

Hopeful for lots of ECC sticks using these.
capybooya@reddit
Will we get 64GB sticks now?
