SK Hynix Inc. saw its shares surge to an all-time high on Thursday after announcing the shipment of samples of its latest high-bandwidth memory (HBM) product, reinforcing its position as a leading supplier in the rapidly expanding artificial intelligence (AI) semiconductor market.
The South Korean memory chip giant revealed that it has begun delivering samples of its 12-layer HBM4E memory chips to major customers. The announcement boosted investor confidence, sending SK Hynix stock up nearly 5% to a record 2,642,000 won. The rally also helped lift South Korea’s benchmark KOSPI index, which gained 0.7% during trading.
HBM4E represents the newest generation of high-bandwidth memory technology, a critical component used in AI processors and data center infrastructure. As demand for advanced AI chips continues to accelerate, memory solutions capable of supporting complex AI workloads have become increasingly important for companies developing next-generation computing platforms.
SK Hynix stated that it will continue working closely with its customers to prepare for mass production of the new memory chips. The company expects strong demand from the AI sector, which has fueled significant growth opportunities for semiconductor manufacturers specializing in advanced memory technologies.
The HBM market remains highly competitive, with SK Hynix, Samsung Electronics, and Micron Technology among the few companies capable of producing advanced high-bandwidth memory at scale. Industry analysts view HBM4E as a key technology for future AI applications, offering enhanced performance and efficiency for AI accelerators and high-performance computing systems.
The latest development follows SK Hynix’s recent agreement with NVIDIA, one of the world’s leading AI chipmakers. Under the partnership, SK Hynix will supply advanced memory solutions for NVIDIA’s most powerful AI processors, further strengthening its presence in the global AI semiconductor supply chain.
As AI adoption continues to expand across industries, SK Hynix is positioning itself to capitalize on growing demand for cutting-edge memory chips, making the company a major beneficiary of the ongoing AI boom.
