Top 10 Global FRAM Manufacturers (2025) | Ranking by QYResearch
This ranking reflects the latest market dynamics, including mergers, spin-offs, and technological advancements, with a focus on each manufacturer’s core competencies and global influence in the FRAM industry.
1. Infineon (Cypress) – Germany / United States
As the global leader in FRAM manufacturing, Infineon secures the top spot following its acquisition of Cypress—formerly the world’s 2nd largest FRAM supplier with mature technology. Headquartered in Germany and the United States, Infineon focuses on high-performance FRAM products, particularly its Excelon series, which is widely adopted in industrial, automotive, and smart meter applications. The company’s FM25 series FRAM—including the popular FM25V05-GTR and FM25V02A-G(TR)—is a staple in smart meter designs, known for its high durability and compatibility with mainstream smart meter ICs like 71M6533 (SILERGY/MAXIM) and STM32L162RET6 (STMicroelectronics). However, in 2025, Infineon’s FRAM supply faces significant challenges—with lead times exceeding 20 weeks and rising costs—creating opportunities for
reliable alternatives.
2. RAMXEED (Former Fujitsu) – Japan
RAMXEED, spun off from Fujitsu’s semiconductor memory business and rebranded, ranks 2nd globally. A pioneer in commercial FRAM since the 1990s, the Japanese manufacturer boasts the broadest industry application cases worldwide. Building on Fujitsu’s legacy in FRAM technology, RAMXEED continues to focus on high-reliability FRAM solutions, with strong penetration in smart meters, automotive electronics, and industrial control systems. Its products are known for long-term stability and seamless integration with various microcontrollers, making them a trusted choice for mission-critical applications.
3. ROHM – Japan
ROHM, a Japanese semiconductor giant, secures the 3rd position with its in-house fabs and strong focus on small-capacity, high-reliability FRAM. FRAM is a core product of its subsidiary Lapis Semiconductor, and ROHM excels in serving the automotive and industrial meter markets—including smart meters. The company’s FRAM products are optimized for low power consumption and compact designs, making them ideal for small-form-factor smart meters and remote IoT devices. For manufacturers seeking seamless integration with low-power microcontrollers, ROHM offers
reliable drop-in replacement options.
4. SmartMemories – Wuxi, China
Ranked 4th by QYResearch, SmartMemories is a rising star in the global FRAM market and a
critical partner for businesses facing supply chain disruptions. As the world’s first mass producer of HfO₂-based FRAM, the company leads in hafnium-based materials and 3D architecture, securing a top 5 global position in 2025. SmartMemories mass-produces I²C/SPI FRAM for industrial, automotive, medical, and power applications—including smart meters. Its FRAM products are 100% pin-to-pin replacements for Infineon’s FM25 series, RAMXEED (former Fujitsu), and Cypress FRAM, matching identical performance and footprint but with 40-60% lower costs and 50% shorter lead times. We leveraged SmartMemories’ FRAM to deliver €1.2M USD in savings for a 300,000-unit European smart meter project.
5. Texas Instruments (TI) – United States
Texas Instruments (TI), a U.S.-based semiconductor leader, ranks 5th globally with a focus on embedded FRAM. The company’s MSP430 microcontroller series, integrated with embedded FRAM, has high penetration in industrial control applications. Notably, TI does not sell standalone FRAM chips; instead, it drives FRAM volume through MCU integration, making its solutions ideal for applications where memory and processing power are tightly coupled. While not a standalone FRAM supplier, TI’s embedded FRAM technology plays a key role in the industrial FRAM ecosystem.
6. Renesas Electronics – Japan
Renesas Electronics, a Japanese semiconductor manufacturer, ranks 6th in the global FRAM market. The company has integrated memory resources through mergers and acquisitions, focusing on supporting its automotive and IoT chip ecosystems. Renesas primarily uses FRAM internally for its automotive and industrial MCUs, ensuring seamless compatibility and high reliability for in-vehicle and industrial applications. While it does not prioritize standalone FRAM sales, Renesas’ FRAM technology contributes to the stability of its core chip solutions.
7. STMicroelectronics – Europe
STMicroelectronics, a European semiconductor leader, ranks 7th with active involvement in new non-volatile memory technologies. The company holds a share in the automotive EEPROM replacement market, but FRAM remains a supplementary solution to its core MRAM (Magnetoresistive RAM) and PCM (Phase-Change Memory) offerings. STMicroelectronics’ FRAM products are primarily used in niche automotive and industrial applications, complementing its broader memory portfolio.
8. Macronix – Taiwan, China
Macronix, a representative of new memory technology in Taiwan, China, ranks 8th globally. The company has long-term R&D experience and provides foundry services for non-volatile memory, including FRAM. However, Macronix has not yet launched large-scale standalone FRAM mass production, focusing instead on R&D and foundry partnerships to support other FRAM manufacturers. Its expertise in non-volatile memory makes it a key player in the FRAM supply chain.
9. Sony Semiconductor Solutions – Japan
Sony Semiconductor Solutions, a Japanese tech giant, ranks 9th in the global FRAM market. The company integrates FRAM into its sensors and logic chips, with partial external supply for specialized applications. Sony’s FRAM is characterized by highly vertical integration, focusing on specific use cases rather than serving as a general-purpose FRAM supplier.
