Micron announced on Thursday that it had started volume production of memory chips using its 3rd Generation 10 nm-class fabrication technology (also known as 1Z nm). The first DRAMs to be made using Micron’s 1Z nm process are 16 Gb monolithic DDR4-3200 and LPDDR4X devices, with Micron expected to broaden their portfolio over time.

Micron’s 3rd Generation 10 nm-class (1Z nm) manufacturing process for DRAM will allow the company to increase the bit density, enhance the performance, and the lower power consumption of its DRAM chips as compared to its 2nd Generation 10 nm-class (1Y nm) technology. In particular, the company says that its 16 Gb DDR4 device consumes 40% less power than two 8 Gb DDR4 DRAMs (presumably at the same clocks). Meanwhile, Micron’s 16 Gb LPDDR4X ICs will bring an up to 10% power saving. Because of the higher bit density that the new 1Z nm technology provides, it will be cheaper for Micron to produce high-capacity (e.g., 16 Gb) memory chips for lower-cost, high-capacity memory sub-systems.

The manufacturer did not disclose the speed bins of its 16 Gb DDR4 DRAMs, but expect Micron to be in the official JEDEC ranges. One of the first products to use the company’s 16 Gb DDR4 devices will be high-capacity (e.g., 32 GB and higher) memory modules for desktops, notebooks, and workstations.

As for mobile memory, Micron’s 16 Gb LPDDR4X chips are rated for transfer rates up to 4266 MT/s. Furthermore, along with offering LPDDR4X DRAM packages with up to 16 GB (8x16Gb) of LPDDR4X for high-end smartphones, Micron will offer UFS-based multichip packages (uMCP4) that integrate NAND for storage and DRAM. The company’s uMCP4 family of products aimed at mainstream handsets will include offerings ranging from 64GB+3GB to 256GB+8GB (NAND+DRAM).

Micron did not disclose where it's producing its monolithic 16 Gb DDR4 and LPDDR4X chips using its 1Z nm technology. Typically, the company kicks off volume production using its latest fabrication processes at its plant in Hiroshima, Japan. Meanwhile, there's also been some speculation among analysts that the company is looking forward to running 1Z production lines this year at its Micron Memory Taiwan (former Rexchip Semiconductor) fab near Taichung, Taiwan.

    So just because some people don't find YOUR humor funny, they are humorless?
  • Spunjji - Monday, August 19, 2019 - link

    What a pompous statement. You defensively insist that other people must be "offended and upset" just for critiquing your pedestrian attempt at satire and pointing out that it adds to the noise component of the signal/noise ratio here. An individual with thicker skin would take it on the chin; you went with projection and posturing. Poor show.

    Speaking of projection. Pot, meet kettle.

    Come off it.

    @Ashinjuka Yep, I guess someone missed the <irony alert> tag in the beginning of that comment, but I bet all of the ElReg readers here saw it immediately.

    Absolutely. A very smart and rich man once said that nobody will every need more than 128k of RAM. It's been downhill ever since.

    You're misquoting the misquote.

    You want the governments to artificially hinder technological advancements?!

    Companies have been moving to smaller nodes for many years and yet ram module makers are still around. They keep making money because the higher capacity modules gradually replace the lower capacity ones in their respective price brackets, people/businesses keep buying them, and the wheel keeps turning.

    Yes. Yes I do. It's stupid that companies are allowed to conduct research without first requesting and obtaining approval from the government of their parent nation. Simply allowing technological advancement to happen naturally as a result of human curiosity is as dangerous and short-sighted. Consider how many airline crashes we could have avoided if someone with half a brain would have brought the hammer down on those Wright brothers back in the early 1900s. Humans were not meant to fly and Icarus already figured that out for us so there's no reason to have to learn that lesson again so many times. And then there's Facebook and that one guy with the dumb hair that now posts comments on Twitter. If we hadn't invented birds, he wouldn't have access to Twitter (which in a small way goes back to flying, but I digress). So no more Twitter! And we may as well get rid of indoor plumbing too so I don't have to run one of those ventilation fans in my bathroom because my bathroom is an outhouse instead.

    You have to get rid of ponies too.
