SK Hynix Developed the World's Highest Density 16 GB NVDIMM

SK Hynix Inc. announced that it has developed the world's highest density 16 GB (Gigabytes) of NVDIMM (Non Volatile DIMM) based on 4 Gb (Gigabit) DDR4 using its advanced 20 nm class technology.

This NVDIMM is able to send DRAM data to NAND Flash whose density is two times bigger than the DRAM in a unanticipated power loss by combining DRAM, NAND Flash and the module controller in a single module. Therefore, it is feasible to save and restore data safely as well as performing on the same level with general DDR4 modules. This new product works at 2133 Mbps and with a 64-bit I/O it processes up to 17 GB of data per second running at 1.2V.
SK Hynix says it has already provided the samples to several customers and the attention to the product from corporations developing server and operating system has been increasing. SK Hynix is expected to create new market demand in heavily increasing big data processing with the new product. The Company plans to start volume mass production of this from the first half of next year to provide the specialized solution to clients who are in need of higher level in data stability.

"The development of the world's highest density 16 GB DDR4 NVDIMM has its significance in leading a new memory solution sector" said Senior Vice President Sung Joo Hong, the Head of DRAM Development. "The Company will further strengthen its competitiveness in server memory market by developing such hybrid modules" he added.

Furthermore, SK Hynix is looking forward to consolidating its leadership in high density DDR4 server market with this development. In April, the Company developed the world's highest density 128 GB DDR4 module based on the industry's highest density DDR4 sole unit of 8 Gb and its 64 GB DDR4 module was the only DDR4 module certified by the latest 'Intel Validation'. The DDR4 interface is expected to be commercialized regularly from 2015 and the main standard in the industry from 2016.

According to Gartner, server DRAM market will grow 37% (on a unit base) in annual average until 2018 following expansion of mobile environment. Plus, according to IHS Technology, the portion of server in DRAM module market (on a unit base) is to expand prominently, which is expected to reach 33% in this year, 41% in the next year and 62% in 2018.
