From Hyundai Electronics to HBM: how SK hynix survived crisis and became an AI-memory leader

SK hynix reached the AI era through one of the more turbulent corporate histories in the semiconductor industry.

The company began in 1983 as Hyundai Electronics. It entered memory manufacturing during South Korea’s push into advanced electronics, later absorbed LG Semicon, survived a severe financial restructuring, separated from the Hyundai name and eventually joined SK Group.

Decades after those upheavals, its development of High Bandwidth Memory placed SK hynix near the centre of the modern AI hardware boom.

Hyundai Electronics entered semiconductors in the 1980s

Founded in 1983, Hyundai Electronics moved quickly into memory manufacturing. SK hynix’s own historical material records pilot production of a 16Kb SRAM in 1984 and mass production of 64Kb DRAM in 1985.

The early strategy mirrored South Korea’s broader industrial ambition: build manufacturing capability in technologies that had previously been dominated by US and Japanese suppliers.

The LG Semicon deal made the company bigger — and more exposed

In 1999, Hyundai Electronics agreed to acquire LG Semicon as part of restructuring in South Korea’s industrial sector after the Asian financial crisis.

The transaction strengthened manufacturing and R&D scale, but it also came during an extremely difficult period for memory pricing and corporate finance.

The enlarged company carried heavy debt into a market famous for violent price cycles.

Hynix emerged from restructuring

In 2001, Hyundai Electronics changed its name to Hynix Semiconductor and separated itself from Hyundai Group.

The new name accompanied a restructuring programme focused on semiconductors while non-core telecommunications and display operations were spun off.

This period was about survival as much as branding. Creditors became deeply involved while Hynix worked to stabilise its finances and maintain technology investment.

SK Group changed the ownership story in 2012

SK Telecom became Hynix’s largest shareholder in 2012, bringing the memory company into SK Group.

Hynix formally became SK hynix in March that year.

The new ownership provided a stronger corporate base for investment in manufacturing, mobile memory, NAND and advanced DRAM technologies.

HBM became the breakthrough that mattered most to AI

SK hynix developed what it described as the world’s first TSV-based High Bandwidth Memory in 2013.

HBM stacks DRAM dies vertically and connects them through microscopic through-silicon vias. The design places large amounts of high-speed memory close to processors while reducing the energy required to move data.

For years HBM remained a specialised technology. AI accelerators changed that.

Large neural networks need enormous memory bandwidth, turning HBM from a niche architecture into one of the most valuable parts of an AI server.

NAND and SSDs added a second memory pillar

SK hynix also built a substantial NAND flash business.

The company expanded further by acquiring Intel’s NAND and SSD operations, creating Solidigm as part of the transaction.

This gave SK hynix a broader position across volatile memory, flash storage and enterprise SSDs.

The AI boom rewarded a long memory bet

The significance of HBM became clear as GPU and AI-accelerator vendors demanded greater bandwidth with every generation.

SK hynix developed successive HBM generations including HBM3 and HBM3E and became a major supplier to the AI infrastructure market.

This did not eliminate the cyclicality of memory, but it shifted part of the business towards products where packaging complexity, thermal design and bandwidth matter as much as raw capacity.

A survival story turned into a technology story

SK hynix’s history is not a simple sequence of product launches. The company passed through acquisition, debt crisis, creditor control, rebranding and a change of corporate parent before emerging as one of the few global manufacturers capable of producing leading-edge DRAM at scale.

As of 18 September 2026, its strategic importance extends beyond PCs and phones. AI systems have made advanced memory an infrastructure technology.
