供应链影响
- AI 服务器需求可能继续挤占先进制程产能，导致 PC DRAM、移动 DRAM、图形 DRAM 和消费 DRAM 等非服务器品类的供应弹性受限，具体影响取决于供应商产能分配节奏和客户长期协议覆盖程度。
- 企业级 SSD 位需求预计同比增长超过 80%，且大部分增量供应已被预定，可能使企业级 SSD 在 4Q26 成为价格涨幅加速的品类，公开市场可售资源可能偏紧，实际影响取决于 CSP 拉货节奏和供应商 QLC 产能释放情况。
- PC OEM 因预期 2027 年 DRAM 供应紧张而提前积极采购，可能使 PC DRAM 在 2026 年第四季度维持价格支撑，但 2027 年 PC DRAM 供应可能因产能转向服务器而下降，具体取决于服务器需求强度和供应商扩产决策。
- 移动 DRAM 和 eMMC/UFS 面临成本上升与终端需求疲弱的双重压力，智能手机品牌可能继续依赖库存并减少增量采购，相关存储品类价格涨幅可能放缓，实际走势取决于终端销售恢复情况和供应商减产执行力度。
- NAND Flash 晶圆价格处于历史高位，下游零售渠道和模组厂采购趋于谨慎，可能限制整体价格涨幅为温和上涨，具体取决于模组厂库存消化速度和供应商基于盈利能力的产能分配策略。
系统解读，仅作为判断线索，不构成备货、出货、涨价或投资建议。
- 传统 DRAM 合约价预计在 4Q26 环比上涨 10–15%，而 NAND Flash 合约价预计上涨 15–20%
- 企业级 SSD 是唯一预计因 CSP 强劲需求而价格涨幅加速的品类
TrendForce 最新存储产业研究显示，DRAM 供应商在 4Q26 继续将先进制程产能优先用于高性能服务器产品，使整体市场维持供不应求。然而，合约价涨幅预计放缓，传统 DRAM 价格预计环比上涨 10–15%。
与此同时，NAND Flash 市场正呈现 AI 需求加速与消费需求疲弱之间的分化，尽管各细分品类价格仍在上涨。整体 NAND Flash 合约价预计环比上涨 15–20%。
对于 PC DRAM，笔记本库存在第四季度日益反映更高的组件成本，拖累终端市场销售。尽管如此，PC OEM 因预期 2027 年 DRAM 供应仍将紧张而继续积极采购，为价格提供持续支撑。在供应侧，DRAM 供应商在 2026 年全年一直按季度履行对 PC OEM 和模组厂的约定量。然而，随着更多产能转向服务器应用，2027 年 PC DRAM 供应可能下降。
在服务器 DRAM 市场，服务器 CPU 供应改善促使 CSP 和服务器 OEM 增加从供应商的位采购，以满足支持代理式 AI 工作负载的通用服务器日益增长的 RDIMM 需求。存储供应商已提高低容量 RDIMM 在产品组合中的占比，以更好地满足客户需求。然而，组件供应、封装测试产能以及前端 DRAM 生产灵活性方面的限制，继续使供应无法完全与需求对齐。因此，服务器 DRAM 预计在 4Q26 仍将供不应求。在定价方面，由于长期协议（LTA）规定的定价机制，部分供应商的涨幅预计将滞后于市场平均。
对于移动 DRAM，成本上升和低成本库存耗尽继续拖累智能手机生产，抑制整体位需求。与此同时，AI 相关应用的强劲需求和更高利润率促使供应商继续将产能转向服务器产品，使移动 DRAM 分配紧张。因此，价格上行趋势依然稳固。然而，由于前几个季度已计入大幅上涨，4Q26 涨幅预计放缓。
在图形 DRAM 方面，部分 PC 品牌正在重新考虑 GDDR6，以降低整体 BOM 成本。与此同时，GDDR7 需求继续主要由 AI 芯片驱动，采购势头优于 PC 市场。
在供应侧，供应商继续缩减 GDDR6 生产并逐步退出市场。GDDR7 产出也仍然有限，因为先进制程产能日益分配给服务器 DRAM 等应用。这些限制预计将使图形 DRAM 价格保持上行轨迹。
对于消费 DRAM，近期增量需求主要来自 SSD 客户，补充了消费网络和电视应用的现有需求。特别是，QLC SSD 需求前景改善，增加了对 DRAM 组件的相应需求。然而，主要供应商仍致力于减产，使市场严重依赖台湾供应商。因此，价格预计将继续上涨——尽管速度放缓。
转向客户端 SSD，PC OEM 可以依赖上半年建立的成品库存和渠道库存来支持第四季度出货，采购主要限于短缺组件。PC 品牌也在减少主流机型的 SSD 容量以降低 BOM 成本，导致采购量和单机平均容量均下降。由于买家持有充足库存且采购需求仍然有限，NAND Flash 供应商采取了更灵活的定价立场，抑制了价格涨幅。
企业级 SSD 市场则呈现出明显不同的景象。随着 CSP 继续扩展 AI 推理基础设施，2026 年企业级 SSD 的位需求预计同比增长超过 80%。需求也在从 LLM 训练转向实际 AI 部署。此外，代理式 AI 的大规模推广正在推动实时检索和缓存数据量指数级增长，而 QLC 在向量数据库中的渗透率持续上升。
作为回应，供应商正在扩大 QLC 产能和高容量产品的供应，同时 PCIe 6.0 的采用正随下一代 AI 服务器平台加速。然而，大部分增量供应已被预定，公开市场可售资源很少。因此，企业级 SSD 价格涨幅预计在 4Q26 加速，使其成为唯一涨幅大于上一季度的存储产品类别。
对于 eMMC/UFS，作为主要需求来源的智能手机品牌，主要依赖现有库存来支持第四季度生产，导致从供应商的增量采购非常有限。电视、机顶盒和可穿戴设备等低利润率产品吸收更高价格的空间更小。
尽管供应商在 AI 驱动的强劲定价势头下寻求更广泛的涨价，但 OEM 仅以维持供应商关系所需的最低采购量回应。结果，谈判实际上缩小为相对小订单量的价格确认。
在 NAND Flash 晶圆市场，价格已达到历史高位，下游零售渠道日益难以承受。这促使主要买家模组厂采取更谨慎的采购立场。
在供应侧，供应商继续基于盈利能力优先分配产能，使整体晶圆供应受限。然而，模组厂采购势头疲弱预计将限制整体价格涨幅为温和上涨。
- Conventional DRAM contract prices are projected to grow 10–15% QoQ in 4Q26, while NAND Flash contract prices are expected to increase 15–20%
- Enterprise SSDs are the only category expected to see price growth accelerate due to strong demand from CSPs
TrendForce’s latest memory industry research reveals that DRAM suppliers continue to prioritize advanced-process capacity for high-performance server products in 4Q26, keeping the overall market undersupplied. However, the pace of contract price increases is expected to moderate, with conventional DRAM prices projected to rise 10–15% QoQ.
Meanwhile, the NAND Flash market is seeing a divergence between accelerating AI demand and weak consumer demand, although prices are still rising across segments. Overall NAND Flash contract prices are projected to increase 15–20% QoQ.
For PC DRAM, notebook inventories are increasingly reflecting higher component costs in the fourth quarter, weighing on end-market sales. Nevertheless, PC OEMs continue to procure aggressively amid expectations that DRAM supply will remain tight in 2027, providing continued support for prices. On the supply side, DRAM suppliers have been fulfilling agreed volumes to PC OEMs and module makers every quarter throughout 2026. However, the PC DRAM supply could decline in 2027 as more capacity shifts to server applications.
In the server DRAM market, improving server CPU availability has prompted CSPs and server OEMs to increase bit procurement from suppliers to meet growing RDIMM demand for general servers supporting agentic AI workloads. Memory suppliers have increased the share of lower-capacity RDIMMs in their product mix to better address customer demand. However, constraints in component supply, packaging and testing capacity, and front-end DRAM production flexibility continue to prevent supply from fully aligning with demand. Server DRAM is therefore expected to remain undersupplied in 4Q26. On the pricing front, increases for some suppliers are expected to lag the market average due to pricing mechanisms stipulated in long-term agreements (LTAs).
For mobile DRAM, rising costs and the depletion of low-cost inventories continue to weigh on smartphone production, suppressing overall bit demand. At the same time, strong demand and higher margins in AI-related applications are prompting suppliers to continue shifting capacity toward server products, leaving mobile DRAM allocations tight. Consequently, the upward price trend remains firmly in place. However, because substantial increases were already priced in during previous quarters, growth is expected to moderate in 4Q26.
In graphics DRAM, some PC brands are reconsidering GDDR6 as a means of reducing overall BOM costs. GDDR7 demand, meanwhile, continues to be driven primarily by AI chips, with procurement momentum outperforming the PC market.
On the supply side, suppliers continue to scale back GDDR6 production while gradually exiting the market. GDDR7 output also remains limited as advanced-process capacity is increasingly allocated to applications such as server DRAM. These constraints are expected to keep graphics DRAM prices on an upward trajectory.
For consumer DRAM, recent incremental demand has come primarily from SSD customers, supplementing existing demand from consumer networking and TV applications. In particular, the improved outlook for QLC SSD demand has increased corresponding demand for DRAM components. However, major suppliers remain committed to production cuts, leaving the market heavily reliant on Taiwanese suppliers. Prices are therefore expected to continue rising—albeit at a slower pace.
Turning to client SSDs, PC OEMs can rely on finished-goods inventories and channel stock built during the first half of the year to support fourth-quarter shipments, limiting procurement largely to components in short supply. PC brands are also reducing SSD capacities in mainstream models to lower BOM costs, resulting in declines in both procurement volumes and average capacity per device. With buyers holding sufficient inventories and purchasing requirements remaining limited, NAND Flash suppliers have adopted a more flexible pricing stance, restraining the magnitude of price increases.
The enterprise SSD market presents a markedly different picture. Bit demand for enterprise SSDs is projected to grow by more than 80% YoY in 2026 as CSPs continue to expand AI inference infrastructure. Demand is also shifting from LLM training toward actual AI deployment. Additionally, the large-scale rollout of agentic AI is driving exponential growth in data volumes for real-time retrieval and caching, while QLC penetration in vector databases continues to rise.
In response, suppliers are expanding QLC capacity and the availability of high-capacity products, while PCIe 6.0 adoption is ramping alongside next-generation AI server platforms. However, most incremental supply has already been committed, leaving little available on the open market. Enterprise SSD price growth is therefore expected to accelerate in 4Q26, making it the only memory product category to see a larger increase than in the previous quarter.
For eMMC/UFS, smartphone brands—the primary source of demand—are largely relying on existing inventories to support fourth-quarter production, resulting in very limited incremental procurement from suppliers. Lower-margin products such as TVs, set-top boxes, and wearables have even less room to absorb higher prices.
Although suppliers are seeking broader price increases on the back of strong AI-driven pricing momentum, OEMs are responding with only the minimum purchase volumes needed to maintain supplier relationships. As a result, negotiations have effectively narrowed to price confirmation for relatively small order volumes.
In the NAND Flash wafer market, prices have reached historical highs that downstream retail channels are increasingly unable to absorb. This has prompted module makers—the primary buyers—to adopt a more cautious procurement stance.
On the supply side, suppliers continue to prioritize capacity based on profitability, keeping overall wafer availability constrained. However, weak purchasing momentum among module makers is expected to limit overall price growth to a modest increase.
