预计 NOR 快闪记忆体市场在 2025 年的价值为 30.5 亿美元,从 2026 年的 32.3 亿美元成长到 2031 年的 42.7 亿美元。
预计在预测期(2026-2031 年)内,复合年增长率将达到 5.75%。

成长势头反映了高级驾驶辅助系统 (ADAS) 内容的不断增加、物联网边缘节点应用的日益广泛以及工业自动化领域投资的重新增长。串行架构因其引脚数少、尺寸紧凑和能源效率高等优势而占据主导地位,使其非常适合空间受限的产品。介面升级,特别是四路和八路 SPI,正在提高读取频宽,从而实现更快的启动速度和更丰富的程式码执行。製造商也在积极回应,推出低电压元件、车规级功能安全认证以及早期 3D NOR 晶片试点项目,这些产品在不牺牲可靠性的前提下提高了密度。
汽车平台正从分散式电控系统 ( ECU) 转型为采用集中式即时韧体的域/区域架构。 NOR 快闪记忆体具有确定性的读取延迟和即时执行能力,这些特性有助于实现功能安全目标。英飞凌获得 ASIL-D 认证的 SEMPER 系列产品展示了整合错误检查和双库冗余如何增强程式码储存的可靠性。 Level 2+ 和 Level 3 功能的普及推动了对 512Mb 至 2Gb 系列 NOR 快闪记忆体产品的需求,预计到 2030 年,汽车 NOR 快闪记忆体的出货量将以 7.13% 的复合年增长率增长。
儘管四路 SPI 已占据物联网程式码储存插槽的一半以上,但八路/xSPI 正在崛起,因为它能将持续读取频宽提升至 400 MB/s,并将下载时间缩短一半。 Synopsys 报告称,与平行记忆体相比,xSPI 减少了引脚数量开销,简化了 PCB 布线并降低了物料成本。 GigaDevice 的 GD25LX 系列可将韧体载入时间缩短 80%,从而实现边缘即时分析。这种吞吐量优势使得工业环境中能够实现更高级的感测器融合和空中升级 (OTA) 功能。
当程式码大小超过 256Mb 时,串列NAND和 eMMC 由于每位元成本低 2-5 倍,正逐渐取代 NOR 快闪记忆体。厂商也纷纷推出混合设计方案,例如千兆装置上的 QSPI NAND,以兼具 NAND 快闪记忆体的经济性,提供与 NOR 快闪记忆体相近的随机读取效能。然而,高密度消费性电子设备在选择 NOR 快闪记忆体之前,仍会继续评估系统总成本。
到2025年,串行产品将占据88.67%的市场份额,这反映了其4-6引脚介面、小型封装和易于组装等优势。并行NOR门在真正需要随机位元组存取的领域仍然很重要,例如抬头显示器和故障安全丛集,但随着微控制器和FPGA厂商转向串行程式码存储,其市场份额正在萎缩。
元件供应商将串列 NOR 快闪记忆体与预先检验的驱动程式堆迭捆绑在一起,从而缩短了 OEM 厂商的产品上市时间。新兴的 3D NOR 快闪记忆体原型首先以串列封装形式出现,为该架构带来了更高的密度和成本优势。因此,在未来十年,NOR 快闪记忆体市场将继续支援串列装置的蓝图。
到 2025 年,四路 SPI 将占总收入的 40.72%,成为主流微控制器的主要驱动力。随着装置容量达到峰值,该细分市场的复合年增长率将放缓,而八路/xSPI 将以 7.15% 的速度增长,满足需要即时启动 Linux 和 AUTOSAR 镜像的工作负载需求。八路 SPI 也符合 JEDEC xSPI通讯协定,使 NOR Flash 能够扩大其在汽车一级供应商和工业系统整合商中的市场份额,这些供应商和整合商更重视引脚相容性而非储存密度。
预计到 2031 年,支援八进位/xSPI 的 NOR Flash 市场规模将显着成长。向下相容的软体介面简化了迁移过程,使设计人员能够在不更改基板设计的情况下逐步提升频宽。供应商正透过将介面演进与安全性和功能安全选项结合,瞄准高端插槽市场。
由于适用于高级资讯娱乐主机和可程式逻辑控制器,容量超过 256Mb 的设备将在 2025 年占据 19.94% 的市场份额,而容量低于 64Mb(高于 32Mb)的零件将以 8.12% 的速度增长,因为它们为韧体物联网节点提供了容量和成本的良好平衡。
高密度晶片蓝图利用堆迭晶粒和新兴的3D布局来缓解平面缩放的限制。然而,32-64Mb插槽的销售成长最为强劲,因为边缘设备的代码扩展与严格的组件成本限制之间存在衝突。供应商提供跨密度等级的引脚相容升级方案,最大限度地减少OEM厂商的重新设计负担。
NOR Flash市场按类型(串行、平行)、介面(例如,SPI单/双介面)、容量(例如,低于2Mb)、电压(例如,3V级)、终端用户应用(例如,家用电子电器)、製程节点(例如,90nm及以上)、封装类型(例如,WLCSP/CSP)和地区(例如,北美)进行细分。市场预测以价值(美元)和数量(单位)为单位。
预计到2025年,亚太地区将占NOR快闪记忆体市场收入的约60.55%,并预计到2031年将显着成长。中国为提高半导体自给自足能力所做的努力,促使大量资金流入55奈米和40奈米製程的量产生产线,并将区域采购转向国内供应商。台湾地区继续占据全球晶圆供应的大部分份额,儘管面临地缘政治风险,仍为外部客户提供支援。日本和韩国透过其历史悠久的晶圆厂做出贡献,铠侠(Kioxia)位于北上的新二期晶圆厂预计将于2025年底开始分阶段增加产能。
北美是一个高端市场,专注于汽车、工业和航太设计。政府在《晶片法案》(CHIPS Act)的支持下,正推动本地晶圆产能提升和先进封装计划的发展,从而实现供应多元化,摆脱对海外代工厂的依赖。美光科技正在拓展其面向汽车应用的NOR记忆体产品组合,而理想汽车的跨域控制器则是中国电动车采用美国製造记忆体的一个例证。
欧洲维持着与NOR功能安全特性相符的严格可靠性和可追溯性标准。总部位于德国的英飞凌正在为一级汽车製造商和工业4.0原始设备製造商建造本土供应链。欧盟政策制定者正在投资建立一个具有韧性的半导体生态系统,这有望增强NOR供应商的需求前景,同时降低该地区对亚洲晶圆代工厂的依赖。
The NOR flash market was valued at USD 3.05 billion in 2025 and estimated to grow from USD 3.23 billion in 2026 to reach USD 4.27 billion by 2031, at a CAGR of 5.75% during the forecast period (2026-2031).

Growth momentum reflects rising content in advanced driver-assistance systems (ADAS), wider use in IoT edge nodes, and renewed investment in industrial automation. Serial architectures dominate because their low pin count, compact footprint, and energy efficiency align with space-constrained products. Interface upgrades-especially Quad and Octal SPI-are lifting read bandwidths, enabling faster boot and richer code execution. Manufacturers are also responding with lower-voltage parts, automotive-grade functional-safety certifications, and early 3D NOR pilots that raise density without sacrificing reliability.
Automotive platforms are migrating from distributed electronic control units to domain and zone architectures that centralize real-time firmware. NOR Flash delivers deterministic read latency and instant-on execution, attributes that underpin functional safety targets. Infineon's SEMPER family, now ASIL-D certified, demonstrates how integrated error-checking and dual-bank redundancy strengthen code-storage resilience. As Level 2+ and Level 3 features proliferate, demand for 512 Mb-2 Gb serial parts is rising, propelling automotive NOR volumes at 7.13% CAGR through 2030.
Quad SPI already powers more than half of IoT code-storage sockets, yet Octal/xSPI is emerging because it pushes sustained read bandwidths to 400 MB/s while halving download times. Synopsys reports that xSPI cuts pin-count overhead versus parallel memory, easing PCB routing and lowering BOM cost. GigaDevice's GD25LX series shows an 80% reduction in firmware load time, enabling real-time analytics at the edge. This throughput benefit is unlocking richer sensor-fusion and over-the-air update features in industrial settings.
When code size grows beyond 256 Mb, Serial NAND or eMMC often displace NOR because they offer two to five times lower cost per bit. Vendors are countering with hybrid designs, such as GigaDevice's QSPI NAND-that deliver NOR-like random read at NAND economics. Nevertheless, high-density consumer devices will continue to evaluate total system cost before selecting NOR.

Serial products supplied 88.67% of the 2025 market share, reflecting their four-to-six-pin interface, smaller packages, and lower assembly complexity. Parallel NOR remains relevant where true random byte access is mandatory, such as heads-up displays and fail-safe clusters, but its footprint is narrowing as microcontroller and FPGA suppliers migrate to serial code storage.
Component vendors bundle Serial NOR with pre-verified driver stacks, accelerating time-to-market for OEMs. Emerging 3D NOR prototypes will debut first in serial footprints, giving the architecture another density and cost tailwind. In this context, the NOR Flash market continues to favor Serial device roadmaps through the decade.
Quad SPI delivered 40.72% revenue in 2025, underpinning mainstream microcontrollers. The segment's CAGR eases as installed bases peak, while Octal/xSPI climbs at 7.15% on workloads that need instant-on Linux or AUTOSAR images. Octal also aligns with JEDEC xSPI protocol, enabling NOR Flash market share gains among automotive Tier 1s and industrial SIs that value pin compatibility across densities.
The NOR Flash market size for Octal/xSPI parts is projected to jump significantly by 2031. Backward-compatible software hooks ease migration; hence, designers can phase-upgrade bandwidth without board redesign. Suppliers are merging interface advancements with security and functional-safety options to target premium sockets.
Devices with greater than 256 Mb captured 19.94% market share in 2025 due to their suitability for sophisticated infotainment head units and programmable logic controllers. Meanwhile, 64-Mb-and-less (greater than 32 Mb) parts grow fastest at 8.12% because they balance capacity and cost for firmware-rich IoT nodes.
Higher-density roadmaps leverage stacked-die or emerging 3D layouts to mitigate planar scaling ceilings. However, volume growth will remain strongest in 32-64 Mb sockets where code expansion in edge devices collides with tight bill-of-materials constraints. Vendors provide pin-compatible upgrade paths across density steps, minimizing redesign effort for OEMs.
NOR Flash Market is Segmented by Type (Serial, Parallel), Interface (SPI Single/Dual, and More), Density (2 Mb and Less, and More), Voltage (3V Class, and More), End-User Application (Consumer Electronics, and More), Process Technology Node (90 Nm and Older, and More), Packaging Type (WLCSP/CSP, and More), and Geography (North America, and More). The Market Forecasts are Provided in Terms of Value (USD) and Volume (Units).
Asia Pacific controlled about 60.55% of the NOR Flash market revenue in 2025 and is projected to expand significantly by 2031. China's semiconductor self-sufficiency drive has drawn considerable capital toward 55 nm and 40 nm serial lines, shifting regional procurement toward domestic vendors. Taiwan continues to supply a significant portion of global wafers, anchoring external customers despite geopolitical risk. Japan and South Korea contribute through long-established fabs; Kioxia's new Kitakami Fab 2 will add incremental capacity starting late 2025.
North America represents a premium segment specialized in automotive, industrial, and aerospace designs. Government incentives under the CHIPS Act are catalyzing local wafer starts and advanced-packaging projects, diversifying supply away from overseas foundries. Micron is broadening its automotive NOR portfolio, with Li Auto's cross-domain controller an illustration of U.S. memory inside Chinese EVs.
Europe maintains strict reliability and traceability standards that align with NOR's functional-safety traits. Infineon's headquarters in Germany anchors a domestic supply chain serving Tier 1 automotive and Industry 4.0 OEMs. EU policymakers are channeling funds toward a resilient semiconductor ecosystem, which could ease the region's dependence on Asian foundries while strengthening demand visibility for NOR suppliers.
