Samsung's cranking out 4GB DDR4 memory chips for faster, more efficient servers

DDR4 memory is finally in mass production, as Samsung Semiconductor announced it’s churning out 4GB 4Gb (512MB) modules, based on “20nm-class” process technology. 32GB sticks like the ones shown above are headed for the premium server market, where Samsung claims their higher speeds (up to 2,667 Mb/s) make for higher performance and 30 percent less power consumption than DDR3. The company claims this is the world’s smallest and highest performing 4Gb RAM chip, and we expect it won’t stop there — when Samsung showcased the technology in 2011 it claimed speeds could eventually reach as high as 4Gbps.

Update: It’s four gigabits, not gigabytes — thanks for the corrections, everyone.

JEDEC announces final DDR4 RAM specification

JEDEC announces final DDR4 RAM specification

A couple of companies have been jumping the gun on DDR4 production, but the JEDEC Solid State Technology Association is finally bringing order to the industry by releasing its official standard for the next-gen DRAM. It calls for “higher performance, with improved reliability and reduced power” — which we roughly take to mean: less gigs for better rigs. The DDR4 per-pin data rate standard is 1.6 gigatransfers per second (GT/s) at the minimum and 3.2 GT/s at the top-end, although this cap is expected to increase in future updates (given that DDR3 also surpassed its initial target). Speeds will begin at 2133MHz, a significant jump from your average DDR3 stick, and will also operate at lower power thanks to the Pseudo Open Drain Interface. Check out the PR below if you want to delve deeper into the specs, and if even that’s not enough to sate you, head to the source link below to tackle the full documentation. Godspeed!

Samsung Samples Industry’s First 16-Gigabyte Server Modules Based on DDR4 Memory technology

Posted in: Today's Chili

Samsung today announced that it has begun sampling the industry’s first 16-gigabyte (GB) double data rate-4 (DDR4), registered dual inline memory modules (RDIMMs), designed for use in enterprise server systems.
Using 30nm-class process technology, Samsung sampled new 8GB and 16GB DDR4 modules in June, in addition to providing them to major CPU and controller makers. The modules will bring the highest density and performance levels to premium enterprise server systems. Samsung previously …
