Samsung faces setback in AI memory race amid labor tensions

April 26 (Asia Today) -- South Korea's race for dominance in high-bandwidth memory, a key component for artificial intelligence chips, is diverging as SK hynix consolidates its lead while Samsung Electronics faces mounting labor tensions.

Industry analysts say the competition is increasingly defined not just by technology, but by timing - with early execution and customer alignment proving decisive in securing long-term market share.

SK hynix recently received a corporate innovation award from the Institute of Electrical and Electronics Engineers, recognizing its leadership in developing and mass-producing successive generations of HBM chips. The company has capitalized on surging demand driven by AI computing, strengthening partnerships with major global clients.

SK hynix is rapidly expanding sales of its HBM3E products while simultaneously preparing for next-generation HBM4, supplying samples to key customers and advancing toward mass production. Analysts say early validation and supply relationships formed at this stage are likely to shape long-term market positioning.

In contrast, Samsung is attempting to close the gap through its own HBM4 development but faces internal challenges. Labor disputes over performance-based bonuses have escalated, with unions warning of a general strike. Industry observers say the tensions could affect not only production but also research, development and customer engagement.

HBM products require close collaboration with customers on customized designs and process validation, making speed of initial response a critical factor. Delays in testing or supply can lead to lost contracts, while early entry into supply chains often results in long-term partnerships.

Analysts warn that Samsung's internal disruptions could weaken its ability to respond during what they describe as a "golden time" in the rapidly expanding AI semiconductor market. If supply stability and development pace falter, customers may shift toward multi-vendor strategies, potentially solidifying SK hynix's advantage.

Experts also point to structural issues behind repeated labor disputes, including disagreements over performance-based compensation. They suggest moving beyond short-term negotiations toward a more transparent system based on objective metrics such as return on invested capital, total shareholder return and economic value added.

Such reforms, they say, could help prevent prolonged conflicts and support the company's competitiveness in a fast-moving global market.
