TipWhy This Matters

SK Hynix’s largest DRAM site outside South Korea, reported to account for roughly 30-40% of the company’s total DRAM production — on the same scale of significance as Samsung’s Xi’an NAND operation, and likewise a reminder that foreign multinationals, not only domestic Chinese firms, make up a large share of chip manufacturing physically located in China. 2025 investment was reported at 581.1 billion KRW, up 102% year-on-year.

Chinese name: SK海力士半导体（中国）有限公司 (SK Hǎilìshì Bàndǎotǐ (Zhōngguó) Yǒuxiàn Gōngsī)

What does this facility make?

DRAM on 12-inch (300mm) wafers; completed conversion to the 1a (4th-generation 10nm-class) process, with roughly 200,000 wafers/month of capacity reported and expansion toward 360,000 wafers/month targeted by the first half of 2030.

Why does it matter?

Like Samsung Xi’an, operates under the same annual US tool-export licensing regime rather than a blanket restriction — both South Korean memory majors were granted 2026 licenses for chipmaking tool shipments to their China plants, replacing the earlier Validated End-User (VEU) waiver system.
