PERSYST™ High-Reliability MRAM Initiative

The PERSYST™ High-Reliability MRAM Initiative by Everspin Technologies focuses on the commercialization and expansion of the EMxxLX HR (High-Reliability) series, an advanced persistent memory solution engineered for highly demanding environments across aerospace, defense, automotive, and industrial applications. The Objective The primary objective of the initiative was to address critical reliability challenges in mission-critical embedded systems. Traditional non-volatile memory technologies often face limitations in write speed, endurance, or long-term reliability, while volatile memory solutions may require additional backup components to preserve data during power interruptions. Everspin developed a unified memory solution that combines high performance with persistent data retention while meeting the stringent requirements of Aerospace, Defense, and Automotive Grade 1 applications. Why It Is Significant & Innovative The PERSYST™ initiative advances the adoption of Spin-Transfer Torque MRAM (STT-MRAM) technology by delivering enhanced density, reliability, and performance for applications where data integrity is essential. • Extreme Environmental Resilience: The EMxxLX HR family achieved AEC-Q100 Grade 1 qualification, supporting operation across temperatures from -40°C to +125°C while maintaining long-term data retention under demanding conditions. • High-Performance Operation: With bandwidth reaching up to 400MB/s through an xSPI interface, the solution enables real-time data logging and instant-on functionality while helping reduce the risk of data loss during write operations. • Proven Reliability in Specialized Applications: During independent radiation testing conducted in collaboration with NASA and the Jet Propulsion Laboratory (JPL), the 64Mb device demonstrated exceptional resilience under radiation exposure. By combining code storage and data memory within a single high-speed persistent memory solution, Everspin Technologies has expanded the role of MRAM technology in next-generation systems, supporting innovations ranging from autonomous vehicles to advanced space exploration applications.
