Samsung Talks DDR6-12800, GDDR7 Development, and HBM3 Volume Production

[AleksandarK]

During Samsung's Tech Day 2021, the company presented some interesting insights about the future of system memory technologies and how it plans to execute its production. Starting with the latest DDR5 standard, the company intends to follow JEDEC documents and offer some overclocking modules that surpass the specification advised by JEDEC. While the DDR5 standard specifies memory modules with 6,400 MT/s, Samsung will develop modules capable of overclocking up to 8,400 MT/s. These are not yet confirmed as they are still in the development phase. However, we can expect to see them in the later life of DDR5 memory.

The company also talked about the DDR6 standard, which is supposedly twice as fast as DDR5. The new DDR6 standard is still in early development, and all we know so far is that the number of memory channels per module is seeing a twofold increase over DDR5 to four channels. The number of memory banks also increases to 64. In addition to DDR6 for desktop and server use cases, the company is also working on Low Power DDR6 (LPDDR6) for mobile applications. While the company's LPDDR5 memory goes into volume production using the 1a-nm process at the beginning of 2022, the LPDDR6 is still in early development. The base speed for DDR6 modules will allegedly arrive at 12,800 MT/s, while overclocking modules will join the party at up to 17,000 MT/s. Mobile-oriented LPDDR6 version is also supposed to come with up to 17,000 MT/s speeds.



Next up, Samsung talked about its memory offerings for graphics, where GDDR and HBM come into play. The new GDDR standard that is supposed to arrive is GDDR6+, which bumps the speed from 18,000 MT/s to 24,000 MT/s. Node of choice for GDDR6+ will be 1z nm, and the Korean giant wants to start manufacturing these modules this month. After this, the company's roadmaps show that the GDDR7 standard will replace GDDR6+ and offer rates of 32,000 MT/s. With GDDR7, there will also be a new feature present called "real-time error protection feature," which is still unknown. Presumably, it is some form of ECC for GDDR or something similar. We are yet to see.

In addition, the company also mentioned that its HBM3 memory will be ready for mass production in the second quarter of 2022, with speeds of 800 GB/s. This memory will target mainly AI applications, and Samsung is working with partners to equip new solutions with HBM3.

What is a 1a-nm or 1z-nm??? WTH??

Also, should we prepare for CL100+ DDR6 modules, considering how ridiculous the timings for DDR5 are??

A being the first letter in the alphabet, I think this is the answer

What a load of BS, once again. 'mumumu its sooo difficult cry cry power shortage virus woopsie price bump!'

Samsung engineers discovered white powdery material I think, as Michael Scott says in The Office they moved some crazy amounts of paper in the 80's, and Samsung just leapfrogged TSMC and Intel and is now doing 1nm node next year.

Talking (PR) is good, but good words come after hard work (porogress). If DDR6 from the release is 12800 then why ddr5 struggles in range from starting from 5xxx... Empty words for me.

We need two decoder rings, one for each hand, one doesn't seem to be enough anymore....

I think this should be consistent. Usually when there is a new DDRX standard, the bandwidth usually doubles. If you look at the current DDR4, it started off with DDR4 2133, whereas you can easily find DDR3 running at 1866 after many years of being in the market. Likewise, DDR4 eventually hit clockspeed of 4000 Mhz, with 3600 being the more common ones. DDR5 is now launching at 4800 Mhz going up to 6000 Mhz. DDR5 is still in its nascent stage, so I would expect it to slowly creep up towards the 10 Ghz mark towards its EOL.

Right now all memory manufacturers can't make enough DDR5 modules as it is. Let's hope by the next generation DDR6 the supply issues are solved.

Does it matter? Memory has gotten faster and faster, never slower.

I see you are man of culture like my me. But sadly, DIY segment is dead now and for upcoming years :}

Yes you're right. Lack of GPUs and DDR5 as well as other PC parts is going to make 2022 a dull year.

In short, everything is "in early stage" and can be safely disregarded. End of story.

DDR5 isnt even super mainstream yet and they are already talking about DDR6... Sheesh. Might aswell keep saving my dollarydoos and wait for the DDR6 platform since DDR5 seems dead in the water so soon.

Well, AMD is in the early stages of Zen 8 planning. Tech companies are always planning ahead. Not just to keep moving forward, but to also keep investors interested in them

Same with PCI-E, gen 5 is just in with Alder Lake and meanwhile gen 6 is getting spec'd.

That's how the industry works. There are stages, stages take time. Doesn't mean they're important to follow as a consumer though.

Better act and do something, than talk, Sammy! Meh!

Fix the VGA shortages. I won't be paying 600 for a Radeon RX 6600 or 1400 for a RX 6800 XT.
Just forget it

Upgrades? I have none

 

[Punkenjoy]

This is still far from coming to the market but it look like the 2020 decades will have much more advancement than the 2010 decades. We will see how price goes...

I think this is due to :

• Return of the competition in both GPU and x86 CPU market
• ARM with Apple giving x86 a hard time
• New packaging techniques
• Return of high margin

We will see but i start to see more and more what Lisa said when she said we enter an new super cycle of computing.

Back to the news I find it interesting that DDR6 will have 4 channel per dimm instead of 2. So a 2 Channel/DIMM system will have effectively 8 channel. If you pair that with a 16 core cpu, you end up with 2 core per memory channel versus 4 with DDR5 and 8 with DDR4. We will see how it go but that will bring back the memory channel in line versus what we had 2 decade ago where a single core CPU had 2 memory channel for itself.

We will see how it will matter too since another development right now is CPU with much larger cache to hide memory latency.

See the date of this report on DDR5 by Anandtech. Or this report on DDR4 by TPU.
