Samsung Hits Volume Production For First 20nm 8Gb DDR4 DRAM Chips And 32GB DDR4 Modules
With its new 8Gb DDR4, Samsung now offers a full line-up of 20nm-based DRAM to lead a new era of 20nm DRAM efficiency that also includes the 20nm 4Gb DDR3 for PCs and the 20nm 6Gb LPDDR3 for mobile devices. Using the new 8Gb DDR4 chip, Samsung began producing the 32GB 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 32GB modules, the new 8Gb chips will allow production of server modules with a maximum capacity of 128GB by applying 3D through silicon via (TSV) technology; moreover, the new DDR4 chip and module use 1.2 volt, which is currently the lowest possible voltage. It won't be long before 8GB and 16GB are standard allotments on flagship products. (Don't blame us for being ready!)
