New partnership will bring Everspin 256Mb PERSYST MRAM into Teledyne HiRel Semiconductors' memory solutions for mission-critical systems
GARLAND, Texas, and CHANDLER, Ariz., Sept. 2, 2026 — Teledyne HiRel Semiconductors, a business unit of Teledyne Technologies Incorporated (NYSE: TDY) and a leading supplier of high-reliability semiconductor solutions, and Everspin Technologies, Inc. (NASDAQ: MRAM), the world's leading developer and manufacturer of magnetoresistive random-access memory (MRAM) solutions, today announced a strategic partnership to accelerate adoption of Everspin's MRAM in aerospace, defense and other demanding systems. This collaboration will begin with the 256Mb PERSYST spin-transfer torque MRAM (STT-MRAM), a non-volatile memory that combines RAM-like speed with the ability to retain data through power loss, system resets and unexpected interruptions.
Through the new partnership, Teledyne HiRel will initially offer Everspin's 256Mb PERSYST STT-MRAM as part of its memory products portfolio for military and aerospace customers, with target applications including avionics, VPX and single-board computer platforms, radar and electronic warfare payloads, satellite electronics, autonomous systems and other next-generation electronic solutions. The agreement also covers other PERSYST STT-MRAM products, including 64Mb and 128Mb options, giving customers additional density choices as program requirements vary.
As component availability, lifecycle planning and long-term supply become greater considerations for programs with long service lives, customers are evaluating persistent memory options that enable fast writes, high endurance and data retention through power loss. These capabilities are especially important for startup, configuration storage, event logging, recovery and other functions that must remain available throughout the product's service life.
Because PERSYST enables frequent writes with high endurance and retains data without battery backup, it can replace or complement NOR flash in applications that need faster updates or power-loss-safe storage, reducing a program's reliance on battery-backed SRAM, hold-up power or capacitor-backed memory schemes. By combining RAM-like access with non-volatility, MRAM can also help simplify architectures that would otherwise require separate volatile memory, non-volatile storage, backup power, wear-leveling strategies or complex data-protection circuitry. Teledyne HiRel will back this new capability with product guidance, screening flows, qualification documentation, procurement support and obsolescence management.
“Aerospace and defense programs require memory solutions that can sustain long operating lifecycles, documented qualification requirements and reliable performance in harsh environments," said Mont Taylor, Vice President of Business Development at Teledyne HiRel Semiconductors. “By adding Everspin's PERSYST STT-MRAM to our non-volatile memory portfolio, we give customers a qualified path to specify persistent memory for their most critical applications."
“PERSYST MRAM delivers a unique combination of endurance, instant-on data retention and high-performance operation," said Sanjeev Aggarwal, President and CEO of Everspin Technologies. “Through our partnership with Teledyne HiRel, customers gain access not only to advanced MRAM technology, but also to the screening expertise and supply continuity needed throughout extended program timelines. This collaboration helps reduce adoption barriers while providing confidence in long-term product availability."
PERSYST MRAM products will ship from Teledyne HiRel Semiconductors' facility in Milpitas, California, with customer availability anticipated in the fourth quarter of 2026.
