SK Hynix has developed a 16GB of NVDIMM (Non Volatile DIMM) based on 4Gb DDR4 using its 20nm class technology. The NVDIMM is a memory technology that combines DRAM and NAND flash to save and restore data in the computer server against any unexpected power loss or system crash.

The 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 2133Mbps and with a 64-bit I/O it processes up to 17GB of data per second running at 1.2V.

SK Hynix says it has already provided the samples to its customers. The Korean company hopes to create new market demand in the big data processing segment.

The company plans to start volume mass production of the 16GB NVDIMM in the first half of next year.

Furthermore, SK Hynix in April developed an 128GB DDR4 module based on 8Gb DDR4 and its 64GB DDR4 module was the only DDR4 module was certified by Intel. The DDR4 interface is expected to be commercialized from 2015 and become a main standard in the industry by 2016.

According to Gartner, server DRAM market will grow 37% (on a unit base) in annual average until 2018 following expansion of mobile environment. IHS Technology claims that 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.
