Everspin Completes Production Qualification for 64Mb xSPI STT-MRAM, Advances 128Mb and 256Mb Densities for High-Reliability Applications

Everspin Technologies in its release shared continued advancements of its high-reliability PERSYST xSPI STT-MRAM portfolio. The company has completed full production qualification for its 64Mb xSPI STT-MRAM device under the AEC-Q100 Grade 1 specification. It is now available for customer orders and supports high-volume production, with inventory accessible through authorized distributors worldwide.

The 128Mb xSPI STT-MRAM is projected to complete production qualification in May 2026. A new 256Mb density variant is scheduled for full production qualification in July 2026, with volume availability anticipated in the second half of 2026.

The expanded portfolio addresses requirements in aerospace, defense, automotive, industrial, and other mission-critical sectors where persistent memory must maintain data integrity under extended temperature ranges and demanding reliability conditions. The 256Mb addition supports higher-capacity designs within the same xSPI architecture, providing scalable options alongside the 64Mb and 128Mb products.

The MRAM market, including STT-MRAM variants, is experiencing significant expansion driven by demand for non-volatile, high-endurance memory in reliability-sensitive applications. According to Grand View Research, th...
