Everspin Technologies is pioneering the next frontier in memory and sensor innovation with its advanced magnetoresistive stack design. At its core, this cutting-edge technology offers unparalleled thermal stability, reliability, and performance enhancements, making it a game-changer for magnetoresistive memory and sensor applications.

This invention centers on a novel seed region, composed of materials such as tantalum and chromium, designed to ensure a non-magnetic and structurally stable foundation. The key lies in its optimized thickness—precisely engineered to enable smoother growth of subsequent magnetic layers while maintaining sharp interfaces. This enhancement directly impacts the device’s performance, preserving essential properties like magnetoresistance (MR) and resistance-area product (RA) even under high-temperature annealing processes.

Above the seed layer, a synthetic antiferromagnetic structure forms the fixed magnetic region, carefully constructed with cobalt, iron, and boron layers separated by coupling materials. These layers work in tandem with dielectric and free magnetic regions to create a robust and responsive magnetoresistive stack. By leveraging advanced materials science, the stack minimizes stress, improves interface quality, and ensures long-term operational integrity.

The implications of this innovation are profound. For spin-torque magnetoresistive random-access memory (MRAM), this architecture translates to faster, more reliable data storage with greater endurance against thermal degradation. In sensors, the enhanced precision and stability expand the possibilities for industrial, automotive, and IoT applications. 

Everspin’s magnetoresistive stack represents a leap in performance and durability, pushing the boundaries of what’s possible in memory and sensor technology. This development not only reinforces Everspin’s leadership in the field but also sets the stage for transformative advancements in data-driven industries worldwide.

Are you developing new technology for an existing application? Did you know your development work could be eligible for the R&D Tax Credit and you can receive up to 14% back on your expenses? Even if your development isn’t successful your work may still qualify for R&D credits (i.e. you don’t need to have a patent to qualify). To find out more, please contact a Swanson Reed R&D Specialist today or check out our free online eligibility test.
