Samsung 8-Gigabit DDR4 at 20 Nanometer Fabbed

Samsung Electronics announced that it is mass producing the industry's most advanced 8-gigabit (Gb) DDR4 memory and 32-gigabyte (GB) module, both of which will be manufactured based on a new 20-nanometer (nm) process technology, for use in enterprise servers.

"Our new 20 nm 8 Gb DDR4 DRAM more than meets the high performance, high density and energy efficiency needs that are driving the proliferation of next-generation enterprise servers," said Jeeho Baek, Vice President of Memory Marketing at Samsung Electronics. "By expanding the production of our 20 nm DRAM line-ups, we will provide premium, high-density DRAM products, while handling increasing demand from customers in the global premium enterprise market."

With its new 8 Gb DDR4, Samsung now offers a full line-up of 20 nm-based DRAM to lead a new era of 20 nm DRAM efficiency that also includes the 20 nm 4 Gb DDR3 for PCs and the 20 nm 6 Gb LPDDR3 for mobile devices.Using the new 8 Gb DDR4 chip, Samsung began producing the 32 GB registered dual in-line memory module (RDIMM) earlier this month. The new module's data transfer rate per pin reaches up to 2,400 megabits per second (Mbps), which delivers an approximately 29 percent performance increase, compared to the 1,866 Mbps bandwidth of a DDR3 server module.

Beyond the 32 GB modules, the new 8 Gb chips will allow production of server modules with a maximum capacity of 128 GB by applying 3D through silicon via (TSV) technology, which will encourage further expansion of the high-density DRAM market. The new high density DDR4, also boasts improved error correction features, which will increase memory reliability in the design of enterprise servers. In addition, the new DDR4 chip and module use 1.2 volt, which is currently the lowest possible voltage.

I would just like to see the price come crashing down on the 8GB modules. 4x8GB is plenty for 99% of home users. 32GB module is insane on an 8 slot board thats 256GB of ram. I guess a few people could utilize a huge ram disk and do all their video editing and rendering directly inside the ram

Are any of the current consumer DDR4 modules built on the 20nm fab?

haha most people can hardly justify having 8GB, though I'm sure I'm going to get a lot of flak for that. But yeah, RAM disks are what I had in mind too. I personally would love to do a RAM disk for a virtual machine, where for probably the first time ever, the CPU would be the bottleneck of the boot process. Of course, that depends on the OS and what you do to it. For example, Windows by default only boots using I think 1 CPU core, but you can tell it to use more through msconfig. If you use sysvinit in linux, it runs the startup processes 1 at a time, but through systemd you get some nice multitasking. It's interesting to me to see what slows down a boot process besides disk load and network establishment.

Better remember to turn off the paging file lest your disk space gets eaten!

Nope iirc they are all done on 30nm at present
