Samsung NAND production in China is set for a technology upgrade under plans announced on October 21, 2026. Samsung Electronics plans to introduce 286-layer V9 NAND chips at its Xi’an plant, targeting monthly output of 5,000 wafers by December 2026 and 40,000 wafers by the end of 2027.
Key Takeaways
- The Xi’an production targets are planned milestones, not completed output increases.
- Samsung’s ninth-generation NAND technology predates the China upgrade, having entered mass production in April 2024.
- SK Hynix is also upgrading Chinese production as both companies face competition from YMTC.

Samsung NAND plan sets two production milestones
The Xi’an project combines a move to more advanced memory chips with a staged increase in wafer output. Samsung’s end-2027 monthly target is eight times the level planned for December 2026, making the production ramp a substantial part of the project rather than a one-off equipment upgrade.
Those figures describe intended production levels. They do not establish that the upgraded line has reached either target, nor do wafer volumes alone indicate the revenue or profit the investment will generate.

|---|---|
| Samsung, Xi’an | Planned technology: 286-layer V9 NAND. |
| SK Hynix, Dalian — current | Existing technology described as 192-layer NAND. |
| SK Hynix, Dalian — upgrade | Planned technology: NAND with at least 240 layers. |
V9 technology has an established production history
Samsung’s April 2024 ninth-generation V-NAND announcement provides the technology background to the Xi’an plan. On April 23, 2024, the company announced that it had begun mass production of its one-terabit triple-level-cell ninth-generation V-NAND.
Samsung said that generation improved bit density by about 50% compared with its predecessor, supported data input/output speeds of up to 3.2 gigabits per second and reduced power consumption by 10%. These are product-generation comparisons, not measurements of the planned Xi’an upgrade’s performance.
The distinction matters: the October 2026 development concerns deploying advanced technology at a particular manufacturing site, rather than the first launch of ninth-generation NAND.
Chinese plants remain a focus of memory competition
SK Hynix is also enhancing its Dalian facility, moving from 192-layer NAND to chips with at least 240 layers. Both South Korean manufacturers face intensifying competition from China’s Yangtze Memory Technologies Co., or YMTC.
The parallel projects show that the competitive response involves upgrading production technology as well as increasing output. The announced layer counts describe the planned chips, but do not by themselves establish manufacturing costs, yields or profitability.
Conclusion
The next stated milestone is Samsung’s target of 5,000 wafers a month at Xi’an by December 2026. Progress toward that level will be the first checkpoint before the larger expansion planned for the end of 2027.
