Editor's comments:- - Hynix designs and makes SSDs for consumer, industrial and enterprise applications and competes in these form factors and interface types:- SSD on chip (eMMC), M.2, 2.5", SATA.

Editor's earlier comments:- SK Hynix is one of the world's largest memory companies. It was late entering the SSD market - offering no SSD products at all as late as 2013. Today - in 2017 - the company offers bland 2.5" SATA SSDs for the consumer and enterprise markets.

In June 2012 - SK Hynix announced it has entered into an agreement to acquire California-based storage solution company Link_A_Media Devices

In August 2010 - Hynix Semiconductor announced it has selected Anobit's SSD controller technology to operate with its own 20nm class NAND Flash chips for use in a new SSD design.

In September 2013 - there was a fire at one of Hynix Semiconductor's memory plants which made 15% of the world's DRAM chips. But production was not seriously affected.

In May 2014 - Hynix acquired Violin Memory's line of PCIe SSDs - for $23 million.

3D nand will face ceiling of vertical scaling soon
Editor:- July 28, 2017 - It takes about 5 weeks to process 64 layer by 64 layer 3D nand flash (with 2017 fab technology) according to a recent video (11 minutes) by Sang-Yun Lee, President & CEO - BeSang (July 23, 2017) which compares the incremental manufacturing costs to the company's proposed 3D super nand technology.

Among other things Sang explains why he thinks the 3D nand bandwaggon will be unable to reduce SSD storage costs in future vertical scaling generations. He says this roadmap was - "A mistake by smart people." ...see the video

Editor's comments:- If San is right with his prognosis on 3D nand - it has ramifications for the expectations about the costs of SSDs in the next few years.

As BeSang has been busy with linkedin blog posts and videos promoting the purported superiority of of 3D super nand and 3D super DRAM I asked the company.

Is Besang looking for flash makers to license the technology? Or will you make devices of your own?

BeSang told me - "BeSang is a fabless NAND product maker and doing IP licensing for DRAM and eDRAM. SK Hynix is the first licensee of 3D Super-DRAM."
