Abstract
More than a decade before generative AI transformed the technology landscape, SK Hynix made a bold and uncertain bet on a memory technology with little proven commercial demand. At the time, the company had only recently emerged from years of financial distress and intense competition within the highly cyclical semiconductor industry. Yet under the leadership of Chey Tae-won and an engineering-driven management culture, SK Hynix continued investing in High Bandwidth Memory (HBM), despite its substantial development costs, technical challenges, and uncertain market potential.
This case study examines how SK Hynix transformed itself from a struggling memory-chip manufacturer into a critical player in the global artificial intelligence ecosystem through a long-term innovation strategy. It explores the company’s early commitment to HBM development, the technological breakthroughs that made commercialization possible, including Through-Silicon Via (TSV) architecture and MR-MUF packaging technology, and the role of cross-border collaboration with Japanese materials suppliers and strategic partnerships with companies such as AMD, Nvidia, and TSMC.
As demand for AI accelerators surged following the rise of generative AI, SK Hynix emerged as a leading supplier of advanced HBM and gained a pivotal position within the global AI value chain. The case invites learners to analyze the relationship between technological innovation, strategic leadership, and competitive advantage while evaluating the risks of long-term investment under uncertainty. It also raises important questions about sustaining technological leadership amid intensifying competition, evolving semiconductor ecosystems, and growing geopolitical tensions between major economies.
