MRAM technology is back in focus after Everspin Technologies announced a $40 million agreement tied to U.S. defense-related applications. The deal matters because it highlights where MRAM is already competitive today: high-reliability, non-volatile memory for systems that cannot afford data loss. This article explains what MRAM is, why the Everspin agreement is significant, and where the technology fits across aerospace, industrial, and edge computing applications.

What Is MRAM Technology?

MRAM stands for Magnetoresistive Random Access Memory. Unlike conventional memory technologies that store data as electrical charge, MRAM stores information using magnetic states. That difference has a practical consequence: data is retained even when power is removed, without requiring any write-back process or battery backup.

The technology combines three properties that are difficult to achieve simultaneously in conventional memory designs: non-volatility (data survives power loss), fast access (comparable in principle to SRAM in many embedded applications), and strong write endurance. For engineers designing systems that must retain critical data reliably over years of operation, that combination is genuinely attractive.

Everspin Technologies (NASDAQ: MRAM), headquartered in Chandler, Arizona, is the leading commercially focused producer of standalone MRAM solutions. In late April 2026, the company announced a $40 million, 30-month agreement with a U.S. prime contractor. Under the arrangement, Everspin will act as a subcontractor providing Toggle MRAM process technology and engineering services for U.S. defense-related programs.

Why Everspin’s $40M Defense Deal Matters

The contract in context

Everspin reported $55.2 million in full-year 2025 revenue. A $40 million agreement spread over 30 months has the potential to materially improve revenue visibility for a company of that scale, if executed as planned. The deal adds a defense-related revenue stream on top of the company’s existing product sales, which grew to $14.1 million in the first quarter of 2026, up from $11.0 million a year earlier.

The broader signal may be strategic rather than purely financial. A U.S.-based MRAM supplier is being pulled into defense-related work at a time when onshore semiconductor manufacturing is receiving more attention from policymakers. Everspin is one of very few companies capable of producing MRAM at meaningful scale within the United States, and the agreement reflects that positioning.

Why defense and aerospace programs consider MRAM

MRAM vs DRAM vs NAND: How the Technologies Compare

To understand where MRAM fits, it helps to compare it against the two memory types it is most often evaluated alongside.

DRAM requires constant power to retain its contents and must be refreshed thousands of times per second. NAND flash retains data without power but has a limited number of write cycles before cells begin to degrade, and write speeds are slow compared to the rates required in many real-time systems. MRAM addresses both constraints, though it currently carries a higher cost per bit than either DRAM or NAND at equivalent densities. Most current deployments are in applications where reliability requirements justify that cost premium.

Where MRAM Technology Is Useful Today

Industrial control and robotics

Automated systems in manufacturing environments benefit from memory that retains operational state through unexpected power events. For example, when a coordinated group of robotic arms loses power mid-cycle, the system needs to know the last confirmed position of each arm before it can safely restart. Memory that preserves that data without any flush operation reduces restart time and eliminates a category of operational risk. MRAM is evaluated for this type of application because it writes fast and retains data without ongoing power.

Aerospace and mil-aero systems

In aerospace applications, memory must often operate across wide temperature ranges and in environments where radiation can affect conventional charge-based storage. Some MRAM architectures are considered well-suited for these conditions. Everspin has referenced design wins in aerospace contexts, including a 2024 contract for radiation-hardened eMRAM development with Frontgrade Technologies, and a satellite systems agreement with Astro Digital announced in early 2025.

Automotive and embedded microcontrollers

Automotive-grade memory must meet strict reliability standards, including wide temperature operation and high write cycle endurance, because vehicle software is updated frequently over the product lifetime. Embedded MRAM is being qualified by multiple automotive semiconductor suppliers for next-generation microcontroller designs. GlobalFoundries, for example, has made automotive-grade embedded MRAM a featured capability on its FDX platform, citing endurance up to 500,000 cycles and sub-10-nanosecond read speed.

Edge devices requiring instant-on non-volatile memory

Edge computing devices, including smart sensors, industrial monitors, and embedded AI systems, often need memory that combines fast write capability, low standby power, and data persistence. Battery-backed SRAM has traditionally served this role, but MRAM eliminates the battery dependency and extends the operational life of the design. Everspin has positioned its products for this application area, and research programs exploring MRAM for AI inference workloads have received funding from academic and government sources, including a Purdue University consortium program announced in early 2025.

What Comes Next for MRAM Technology

The Everspin agreement is a data point in a longer trend. MRAM technology has been in commercial use for over a decade in industrial and aerospace applications, but the combination of advancing process nodes, growing demand for reliable edge computing memory, and renewed emphasis on domestic semiconductor supply chains is pulling it into a broader set of conversations.

Competition is also intensifying. Samsung’s 8nm MRAM work signals that the technology race is moving beyond niche deployments. GlobalFoundries reported a meaningful increase in automotive MRAM design wins in early 2026. Market research firms project strong growth in MRAM adoption, though forecasts vary significantly across sources. The direction is consistent even where the exact numbers differ.

For engineers, the practical question is whether MRAM fits a specific design requirement better than the alternatives currently in use. For technology observers, the more interesting question is how quickly embedded MRAM at advanced nodes becomes a standard option in automotive and industrial microcontrollers, and what that means for the memory supply chain overall. Both questions are worth watching over the next two to three years.
