SK Hynix is spending $38 billion to build two new chip fabs

SK Hynix, a global leader in memory manufacturing, has announced a staggering $38 billion investment to expand its production capabilities. The South Korean tech giant plans to build two new advanced semiconductor fabrication plants in Yongin and Cheongju, South Korea. These facilities, codenamed Y2 and M17, respectively, aim to boost SK Hynix's production of both DRAM and NAND flash products.

Y2, slated to commence construction in July 2027, will initially increase SK Hynix's DRAM output capacity. The first cleanroom for Y2 is expected to be operational by June 2029, enabling the production of high-bandwidth memory solutions and next-generation DRAM chips. Meanwhile, the Cheongju M17 plant, under construction since February 2027, will primarily focus on NAND Flash chip manufacturing. Its first cleanroom is set to begin operations in December 2028.

SK Hynix acknowledges the current high demand for high-bandwidth memory (HBM) in the AI sector, particularly from companies like Nvidia, AMD, and other major vendors. This surge in demand is attributed to the expanding AI infrastructure and the increasing need for AI accelerators in data centers. Additionally, SK Hynix notes a rapid increase in demand for NAND flash chips, primarily used as cache storage in AI inference workloads and expected to be further driven by agentic and physical AI applications such as robots.

The company's CEO commented that SK Hynix aims to become a key partner in AI infrastructure, contributing to the stability of the global AI semiconductor supply chain. With the new Y2 and M17 plants set to enhance the company's production capacity, SK Hynix hopes to address the ongoing supply chain crisis that has plagued the industry since its onset.
