Samsung Electronics Unveils Industry's Highest-Capacity 12nm-Class 32Gb DDR5 DRAM

collaboration with diverse industries and support various applications
Samsung Electronics, a world leader in advanced memory technology, today announced that it has developed the industry's first and highest-capacity 32-gigabit (Gb) DDR5 DRAM using 12 nanometer (nm)-class process technology. This achievement comes after Samsung began mass production of its 12 nm-class 16Gb DDR5 DRAM in May 2023. It solidifies Samsung's leadership in next-generation DRAM technology and signals the next chapter of high-capacity memory.

"With our 12 nm-class 32Gb DRAM, we have secured a solution that will enable DRAM modules of up to 1-terabyte (TB), allowing us to be ideally positioned to serve the growing need for high-capacity DRAM in the era of AI (Artificial Intelligence) and big data," said SangJoon Hwang, Executive Vice President of DRAM Product & Technology at Samsung Electronics. "We will continue to develop DRAM solutions through differentiated process and design technologies to break the boundaries of memory technology."
A 500,000 Fold Increase in DRAM Capacity Since 1983
Having developed its first 64-kilobit (Kb) DRAM in 1983, Samsung has now succeeded in enhancing its DRAM capacity by a factor of 500,000 over the last 40 years.

Samsung's newest memory product, developed using cutting-edge processes and technologies to increase integration density and design optimization, boasts the industry's highest capacity for a single DRAM chip and offers double the capacity of 16Gb DDR5 DRAM in the same package size.

Previously, DDR5 128 GB DRAM modules manufactured using 16Gb DRAM required the Through Silicon Via (TSV) process. However, by using Samsung's 32Gb DRAM, the 128 GB module can now be produced without using the TSV process, while reducing power consumption by approximately 10% compared to 128 GB modules with 16Gb DRAM. This technological breakthrough makes the product the optimal solution for enterprises that emphasize power efficiency, such as data centers.

With its 12 nm-class 32Gb DDR5 DRAM as a foundation, Samsung plans to continue expanding its lineup of high-capacity DRAM to meet the current and future demands of the computing and IT industry. Samsung will reaffirm its leadership in the next-generation DRAM market by supplying the 12-nm-class 32Gb DRAM to data centers as well as to customers that require applications like AI and next-generation computing. The product will also play an important role in Samsung's continued collaboration with other key industry players.

Mass production of the new 12 nm-class 32Gb DDR5 DRAM is scheduled to begin by the end of this year.

Yes, 64GB DDR5 modules for home PC is on the way with 16*4GB ICs (dual sided).

I would love 256GB RAM on my home PC given photo editing programs do seem to follow the rule the more the merrier with RAM.

Not sure that this size will be supported from today's consumer hardware. Is possible but I'm not sure. In the embedded specifications of AMD Phoenix exist support up to 256GB RAM but for the other today's hardware I didn't see support for more than 128GB(192GB is added in some motherboard specs).

2*64 will be very welcome as my current 4*32 do only 4000mhz...

Maybe next gen CPUs given current gen seem to be struggling with all 4 slots occupied.

That means we will see 2x64gb? because 2x32gb has been for awhile. We recently got 2x48gb.

The option to go past 128gb without having to go to HEDT would be great. For the work I do, having more RAM is always nice but I have absolutely no need for more PCIE lanes or higher core counts that are offered by HEDT. Having to pay extra for a CPU with similar performance and a lot more for the motherboard has always been prohibitive for me just for a RAM capacity increase. Suppose that's the "professional tax".

There's a good chance that yes, we're going to see 256 GB supported. At the time the CPU and mobo specifications were made, 128 GB was the maximum achievable with DIMMS in existence. Then, it was 192 GB.

Supporting larger capacity dies doesn't require many resources in the IMC as long as the number of banks and ranks stays the same. It's totally possible that the hardware can even handle 48 Gbit and 64 Gbit dies when they become available in a few years ... but not without an updated BIOS of course.

I have reason to assume that AMD Ryzen 8000 and Intel Arrow lake will have such support out of the box and there will be offers on the market that can fill this capacity even when they start being offered in stores.

Driving four sticks is harder than driving two sticks and two empty slots without termination, which in turn is harder than driving just two sticks. That's simple physics.

That's not only true when the IMC is sending data. A DIMM also sends data. In a four-slot board, two slots share the same wires, so a DIMM has to drive the IMC but inevitably also the other DIMM (or an empty slot).

You mean solo 64GB modules?
You can already have them:
  • KINGSTON 64GB DDR5 4800MHz CL40 KTH-PL548D4-64G
  • MICRON 64GB DDR5 4800MHz CL40 MTC40F2046S1RC48BA1T

Same here, now you have to buy the ridiculously overpriced Threadrippers if you want more than 128GB RAM in your rig.

No, these modules are not intended for home mainstream PC.

Woould absolutely love to get at least 2 x 64GB sticks in my next PC build also for photo/video editing. Just the upgrade from 32GB to 64GB I recently did made a huge difference when using Adobe's pathetically coded software full of memory leaks.

Just a briefest offtopic question: A few years ago, Photoshop was known for requiring a pagefile to work, no matter what. Is this still the case with PS or any other Adobe software? I mean, I'm not advocating disabling the pagefile but applications should not require it when there's plenty of RAM.
