What happened
Samsung Electronics and SK hynix confirmed that work is under way to modernize NAND flash production at their respective factories in China, following a Reuters report based on four people familiar with the plans. Neither company publicly detailed the production arrangements described in that report, although both said the work is being coordinated with Washington and that it complies with U.S. export rules.S1 The stated objectives include serving demand associated with artificial intelligence and limiting the competitive advantage of Yangtze Memory Technologies Co, also known as YMTC.S1
Samsung's conversion at Xian reportedly moves production from roughly 200-layer chips toward 286-layer V9 NAND under its Monami project. The report said the plant represents about 40% of Samsung's worldwide NAND output and could reach 5,000 wafers monthly in December 2026, followed by 40,000 wafers per month in December 2027. Samsung characterized the work as a technology conversion at an existing site rather than a capacity expansion or construction of another factory.S1
SK hynix is reportedly considering a shift from 192-layer production at Dalian to products with at least 240 layers. People familiar with the plan said the Dalian site is authorized to produce chips with no more than 240 layers, while research above 300 layers could require separate Washington approval. SK hynix already sells NAND products reaching 321 layers outside China.S1
The licensing position remains unresolved. U.S. rules adopted since 2022 require annual approvals for specified U.S.-made chipmaking equipment, and the Bureau of Industry and Security said in 2025 that it did not plan to issue licenses for technology upgrades or capacity expansion at the factories in China. Reuters could not establish how many required approvals have been granted.S1 Omdia figures cited by Reuters placed YMTC's second-quarter share of China's NAND market at 38.5%, compared with 33.5% for Samsung and 17% for SK hynix.S1
| Metric | Reported value |
|---|---|
| Samsung Xian share of global NAND output | About 40% S1 |
| Target Xian output in December 2026 | 5,000 wafers per month S1 |
| Target Xian output in December 2027 | 40,000 wafers per month S1 |
| YMTC share of China's second-quarter NAND market | 38.5% S1 |
Background timeline
- - Reuters reported that SK hynix linked a proposed American factory to Washington's willingness to approve additional equipment for its Dalian operation.S1
- - TickerGrove reported the NAND modernization plans and the unresolved export-license position.S1
- - Samsung's reported Monami schedule identifies 5,000 wafers per month as the Xian output target.S1
- - The same schedule identifies 40,000 wafers per month as the Xian output target.S1
XAIPART take
Technical impact
XAIPART analysis: Moving toward higher-layer NAND can improve storage density and reduce the cost per bit, which may affect qualification decisions for SSDs and other high-capacity embedded designs. However, buyers should not treat higher layer counts as proof of better total cost because controller, firmware, endurance, and thermal requirements still determine application-level performance.
Market impact
XAIPART analysis: License uncertainty creates a split between announced manufacturing plans and executable supply. Procurement teams should map each relevant NAND family to its fabrication origin and approval status rather than assuming that every announced node conversion can proceed on schedule.
Action
XAIPART analysis: Buyers should request supplier confirmation of wafer starts, product-node availability, and equipment approvals for Xian and Dalian allocations. Designers evaluating high-layer parts should also request samples, qualification data, and a documented fallback source before switching approved BOM components.
XAIPART Forecast
XAIPART analysis: XAIPART expects Samsung's Xian site not to reach the reported target of 40,000 wafers per month by 2027-12-01 unless additional U.S. equipment approvals are confirmed. If published output reaches 40,000 wafers per month by that date, this forecast is wrong.
Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. The production details and current license status remain unconfirmed because the article relies on a single Reuters-based report and anonymous sources.
