SK Hynix reveals 128GB DDR4 memory module [UPDATED]

UPDATE: The initial news-story contained an image of an SK Hynix memory module which did not feature 128GB capacity. As SK Hynix has released the correct images of its new memory modules, we can now publish the photos of 128GB DDR4 memory sticks.

SK Hynix on Monday unveiled the industry’s first 128GB DDR4 memory module aimed at next-generation servers based on Intel Xeon E5 “Haswell” microprocessor. The new module will not hit the market until sometimes next year.

The 128GB DDR4 memory module from SK Hynix is based on 8Gb DDR4 memory chips made using 20nm process technology. The module works at 2133Mb/s with 1.2V voltage and has a 64-bit I/O bus width. This memory stick has double density compared to existing 64GB by taking advantage of TSV (through silicon via) technology.

SK Hynix plans to start volume production of 64GB and 128GB memory modules based on 8Gb DDR4 memory chips in the first half of next year.

“The development of the world’s first 128GB DDR4 module has its significance in opening ultrahigh density server market” said Sung Joo Hong, the head of DRAM development at SK Hynix. “The company will further strengthen its competitiveness in premium DRAM sphere with the development of high density, ultrahigh speed and low power consuming products” he added.

According to Gartner, server DRAM market will grow 37% in annual average until 2018. The new DDR4 memory is expected to be certified by customers in this year and is anticipated to be commercialized regularly from 2015. It is projected that the DDR4 will become the mostly used memory standard sometimes in 2016.

KitGuru Says: Keeping in mind that modern server processors can have more than ten x86 cores, 128GB memory modules will truly be needed to fully take advantage of upcoming microprocessors’ potential.
