Chung Ju-yung built Hyundai Group into a Korean industrial conglomerate through sheer force of will and government backing, and in 1983 he made a decision that most of his advisors considered reckless: entering the semiconductor business at a moment when Korean memory producers were years behind Japanese competitors who had already mastered 64Kb DRAM production. He founded Hyundai Electronics in Icheon, set a deadline of six months to produce a functional 64Kb DRAM chip, and the engineering team delivered it — months ahead of schedule and far faster than any outside observer had predicted possible.
That 1983 founding put the company on a trajectory defined by capital intensity and cyclical vulnerability that has never fully changed. Memory semiconductors require continuous investment in new fabrication nodes to remain competitive, and the margins to fund that investment evaporate during the frequent price collapses that characterize the commodity memory market. Hyundai Electronics nearly went under twice before the business stabilized as an independent entity.
The company was renamed Hynix Semiconductor in 2001 after separating from the Hyundai Group, and the separation was financially traumatic — the company carried enormous debt loads from the DRAM overcapacity crisis of the early 2000s and required creditor-led restructuring to survive. It was during this period that the company's identity as an independent entity, rather than a Hyundai subsidiary, fully crystallized. The engineers stayed even when the balance sheet was precarious.
SK Group's 2012 acquisition brought the balance sheet stability that allowed Hynix — renamed SK Hynix — to invest seriously in the advanced DRAM nodes that would eventually produce the HBM technology. The 1992 milestone of producing South Korea's first 64Mb DRAM chip established the company's credibility as a technology leader; the HBM3E design win with Nvidia thirty years later validated that the bet Chung Ju-yung made in 1983 had compounded into something extraordinary.
Hyundai Electronics was founded in 1983 under the Hyundai Group led by Chung Ju-yung. Following Hyundai Group's financial restructuring, the semiconductor unit was renamed Hynix Semiconductor in 2001 and later acquired by SK Group in 2012, becoming SK Hynix Inc.

Following the 1997 Asian Financial Crisis, the South Korean government orchestrated the merger of Hyundai Electronics and LG Semiconductor to create a single, stronger entity capable of surviving the economic collapse and competing globally against Samsung and Japanese manufacturers.
SK Hynix traces its roots to Hyundai Electronics Industries, founded in 1983 by Chung Ju-yung as part of the Hyundai chaebol's diversification into semiconductors. Through the 1990s the company built a global DRAM business and absorbed LG Semicon in 1999 during the post-Asian financial crisis Big Deal restructuring, briefly becoming the world's second largest DRAM maker. Crushing debt and the 2001 memory price collapse pushed Hynix Semiconductor, as it was renamed in 2001, into a creditor workout led by Korea Exchange Bank and a syndicate of domestic banks. Through the 2000s the company operated under creditor control, surviving an attempted Micron acquisition in 2002 that collapsed at the board level, and undergoing repeated dilutive recapitalizations. SK Group, controlled by chairman Chey Tae-won, acquired a controlling 21.05 percent stake from the creditor consortium in February 2012 for roughly 3.4 trillion won and renamed the company SK Hynix. The SK era brought capital discipline, aggressive capex into Icheon and Cheongju, and a strategic pivot toward NAND flash. The 2020 Intel NAND and SSD deal, closed in two phases through 2025, and the 2023 to 2024 HBM3 ramp for Nvidia have since reshaped SK Hynix into a memory champion alongside Samsung.
After Hyundai Electronics was rebranded Hynix Semiconductor in March 2001, a glut driven DRAM price crash and 8 trillion won of debt forced the company into a creditor led workout in October 2001. Korea Exchange Bank, Woori Bank and a syndicate of more than 100 creditors swapped roughly 3 trillion won of debt for equity and seized operational control. The workout era from 2001 to 2012 forced Hynix to sell its non-memory foundry business, which became MagnaChip in 2004 through a Citigroup Venture Capital led carve-out for about 954 million dollars. It also pushed the company to standardize on commodity DRAM and NAND, mothball higher cost fabs, and accept punishing US and EU countervailing duties imposed in 2003 to 2006 on the grounds that creditor support was an unlawful subsidy. By the time SK Group acquired its stake in February 2012 for 3.4 trillion won, Hynix had paid down most workout debt and exited creditor management. The decade of austerity left a leaner cost structure and a survivor mindset that still shapes SK Hynix's emphasis on yield, fab utilization and counter cyclical investment in HBM and advanced DRAM nodes.
The renaming to SK Hynix was completed on 26 March 2012, shortly after SK Telecom and affiliated SK Group entities closed their acquisition of a 21.05 percent controlling stake from the creditor consortium on 14 February 2012 for approximately 3.4 trillion won, or about 3 billion dollars at the time. SK Group, Korea's third largest chaebol led by chairman Chey Tae-won, used the deal to add a memory semiconductor pillar alongside its telecom, energy and chemicals businesses, betting that DRAM and NAND would become foundational to mobile and cloud computing. The rebrand from Hynix Semiconductor to SK Hynix Inc. signaled the formal end of the eleven year creditor workout and folded the company into SK Group governance, including SK ICT Family branding alongside SK Telecom and SK Broadband. Operationally the new owners injected fresh capex into the M14 fab project, accelerated the migration to 25 nanometer and below DRAM, and committed to NAND scale up at the M11 and M12 fabs in Cheongju. The SK name carried weight in Korean capital markets and helped repair Hynix's credit profile, with ratings agencies upgrading the company within 18 months of the deal.
SK Hynix's manufacturing is concentrated in two Korean campuses plus expanding overseas sites. The Icheon campus south of Seoul houses the M10, M14 and M16 fabs for leading edge DRAM, with M16 commissioned in 2021 as the world's largest DRAM fab using EUV lithography on the 1a-nanometer node. The Cheongju campus in North Chungcheong Province runs the M11, M12 and M15 fabs focused on NAND flash, including the M15X expansion approved in 2022 with planned investment of about 15 trillion won. Overseas, the Wuxi DRAM fab in China, acquired and expanded since 2006, accounts for roughly half of SK Hynix's DRAM output, while the Dalian NAND fab transferred from Intel as part of the 9 billion dollar 2020 deal became the core of Solidigm. SK Hynix has also committed to a 122 trillion won, four fab semiconductor mega cluster in Yongin announced in 2022 with first construction in 2025 and first fab operation targeted around 2027. In the United States, the company committed in April 2024 to a 3.87 billion dollar HBM and advanced packaging plant in West Lafayette Indiana, supported by 458 million dollars in CHIPS Act funding.
SK Hynix began HBM development in 2013 alongside AMD, taping out the industry's first HBM1 product that year. While Samsung de-prioritized HBM during the 2019 to 2020 downturn, SK Hynix kept investing through HBM2, HBM2E and HBM3, certifying HBM3 with Nvidia in 2022 for the H100 accelerator. That timing proved decisive when generative AI demand exploded in 2023, and SK Hynix emerged as the sole qualified HBM3 supplier to Nvidia for most of 2023 before Micron and Samsung began catching up in 2024. By the third quarter of 2024 SK Hynix held roughly 50 percent of HBM market share and HBM revenue exceeded 30 percent of company DRAM sales, contributing to record quarterly operating profit of 7 trillion won in the third quarter of 2024. The company shipped HBM3E 8 high stacks to Nvidia in March 2024 ahead of competitors, qualified 12 high HBM3E in late 2024, and pre announced HBM4 sampling for 2025 with mass production targeted in the second half of 2025. SK Hynix has stated that its HBM capacity is fully sold out through 2026.
