Samsung Electronics succeeded in manufacturing the world’s smallest, yet fastest, DRAM for PCs. The accomplishment is expected to accelerate the development of DDR4. The company announced on August 30 that it started commercial production of 20nm-class DDR4 modules that cane be mounted on high-capacity servers in next-gen data centers.
The DDR4 DRAM module is expected to reshape the global memory chip market in five years, like the commercial-scale production of 50nm-class DDR3 DRAM chips that started in 2008. Although it is the smallest in the world, the data processing speed is 2,667Mb/s, faster than any other of its kind. Compared to 20nm-class DDR3 DRAM, it consumes about 30% less power while processing data at a speed 1.25 times faster.
When the data processing speed is increased, the system performance of high-capacity servers is improved, but total power consumption is significantly reduced. In addition, overall performance can be maximized at minimum cost, so that the investment can be made much more efficient.
Once Samsung Electronics begins to supply the 20nm-class 32GB DDR4 modules in large quantity, the focus of the server market, which is revolving around 30nm-class 8GB DDR3 modules now, is likely to shift rapidly to the higher-performance, lower-power DDR4 DRAM.
