Samsung will spend 105.7944 trillion VND on a semiconductor test fab in Thai Nguyen Province, Vietnam, its second major back-end base for exporting packaged DRAM and NAND memory. Documents submitted to the People's Committee of Thai Nguyen Province, reported by Sedaily, show the Korean giant set up a dedicated subsidiary, Samsung Vietnam Semiconductor (SVS), in March to run the project.

The plant will occupy 265,895 square meters — roughly 37 soccer fields — in the CN-11 and CN-12 zones of Yen Binh Industrial Park, in the same complex as Samsung's Vietnamese smartphone plants. The site offers logistics links to Noi Bai International Airport, seaports and major roads.

What will the fab actually do?

The facility performs final testing, not wafer fabrication. Packaged DRAM and NAND chips arriving from Samsung's production lines will undergo performance screening under normal and harsh operating conditions. Defective parts get removed before the remaining chips ship to customers.

Samsung has already fixed the schedule:

• V1 line (first floor): equipment moves in July 2027; operations begin in Q4 2027.
• V2 line (second floor): equipment moves in May 2028; operations begin in October 2028.

How is the 105.8 trillion VND financed?

The two-phase build relies on three funding sources:

• 34.6% from Samsung affiliates.
• 2.5% from investors.
• The remaining 66.6401 trillion VND from profits generated by Samsung's future operations in Vietnam.

That structure ties the project's completion to Samsung's existing Vietnamese manufacturing footprint, which the company has built around its smartphone assembly operations in the same industrial park.

Why Vietnam, and why now?

The source framing points to booming AI infrastructure, which keeps pushing memory demand upward. A second overseas test hub lets Samsung diversify its export routes and improve supply chain flexibility, rather than concentrating final testing in a single geography.

With equipment installation starting in under a year from the reported timeline and full two-line operation targeted for October 2028, the Thai Nguyen fab positions Samsung to scale memory output validation alongside AI-driven demand growth through the end of the decade.
