Everspin Technologies, a global leader in magnetoresistive random access memory (MRAM) solutions, announced further advancements in its high-reliability PERSYST xSPI STT-MRAM lineup. The company has completed full production qualification for its 64Mb MRAM and introduced a new 256Mb density to the portfolio.
The high-reliability 64Mb xSPI STT-MRAM now meets the AEC-Q100 Grade 1 standard, is available for customer orders, and supports high-volume production. Stock is ready through Everspin’s authorized distributors worldwide.
The 128Mb xSPI STT-MRAM is expected to complete production qualification in May 2026, and a new 256Mb option is scheduled to complete full production qualification in July 2026, with volume availability expected in the second half of 2026.
“Advancing our high-reliability product family through production qualification and expanding density options reflects steady progress against our technology roadmap,” said Sanjeev Aggarwal, president and CEO of Everspin Technologies. “Customers designing long-lifecycle systems require validated memory solutions with predictable performance, and we are extending the PERSYST platform to meet those needs across a wider range of densities.”
The addition of the 256Mb density enables higher-capacity persistent memory designs within the same xSPI-based architecture. Together with the 64Mb and 128Mb xSPI STT-MRAM products, the expanded Hi-Rel portfolio provides scalable options for applications operating across extended temperature ranges and demanding reliability environments.
“Production qualification provides the level of confidence required for space and satellite programs moving into long-term deployment,” said Billy Wahng, Chief Technology Officer at Astro Digital. “Everspin’s focus on endurance, data integrity and radiation tolerance addresses the challenges of operating in unpredictable environments.”
These milestones represent continued execution of Everspin’s roadmap to broaden its HR MRAM portfolio for aerospace, defense, automotive, industrial and other mission-critical applications.
