Semiconductor is a drive engine and a future of the IT industry

Semiconductors are essential to all IT products, and its performance often determines the performance of the final products. SK hynix is the global leader in producing semiconductor, such as DRAM and NAND flash and System IC including CMOS Image Sensors. Since pilot production of Korea’s first 16Kb SRAM in 1984, SK hynix consistently led the industry with smaller, faster and lower power semiconductor.
As the second largest manufacturer of memory semiconductor, SK hynix is at the forefront of the IT industry.

It is common to see people using their smartphones and tablet PCs. Those IT devices become more pervasive as new imaginative and innovative IT products continue to grab imagination and ‘desires’ of consumers. More innovative IT device such as smart car, keyboard and surface computer without mouse will enlarge the range and demand of the semiconductor.
SK hynix has recorded high performance by tracking and foreseeing the market change. On year 2011 base, SK hynix ranked 2nd position with a 23% worldwide market share in DRAM market. It has also a 10% NAND Flash market share. It also takes 8th position in global semiconductor market. SK hynix will strengthen the world’s top level of technology and continuously diversify the product portfolios.

Our Businesses


Through our tireless focus on R&D and quality control, SK hynix manufactures highest quality and highest performance DRAM products.
Our principal products include dynamic random-access memory (DRAM) for PCs, laptops and servers, low-power mobile DRAMs, high-speed graphic DRAMs for graphic data processing and consumer DRAMs for the full spectrum of digital devices. Our products support wide array of interfaces, including DDR, DDR2, DDR3 and DDR4 interfaces, to meet our customer needs.
While we at SK hynix strives to meet all of our customers’ needs through innovative R&D and leading edge technology, we are particularly focused on high-capacity, high-performance, low-power premium products to drive our future growth.

NAND Flash

While NAND flash was initially used for simple data storage in MP3 players, PMPs, digital cameras and navigational devices, its applications have since expanded to include smartphones, tablet PCs and solid state drives (SSD). As the technology and market share leader, SK hynix is staying ahead of rapid NAND flash industry developments through introduction of higher-speed, higher-capacity products.
SK hynix’s single-level cell (SLC), multi-level cell (MLC) and leading-edge triple-level cell (TLC) products come in wide range of capacities from 128Mb to 512Gb. In addition to our stand along NAND flash products, we provide the best NAND solutions to meet a variety of customer needs through our multi chip package (MCP), embedded flash and SSD solutions.


SK hynix reentered the CMOS image sensor (CIS) business at the end of 2007. CMOS image sensors serve as electronic film and electronic eyes for a variety of IT and consumer devices. While it is a non-memory semiconductor, similarity of production process to that of semiconductor memories gave SK hynix competency to successfully enter the CIS business.
Applications for CIS are expected to dramatically rise in the future. With SK hynix’s CIS products scheduled to be adopted by a wide range of applications--including web cameras, miniaturized medical imaging equipment, and mobile phones—we plan to lead a new chapter in CIS market through high-resolution sensors manufactured on most advanced process technology to meet diverse needs of our customers.
