Advanced Microsensor (AMS)

Advanced MicroSensors Corporation (AMS) is a semiconductor foundry, which develops and fabricates MEMS and spintronics solutions. AMS was founded in 1999 and is based in Massachusetts, USA.

AMS's magnetic sensor product line uses magnetoresistive (AMR, GMR) materials and magnetic tunnel junctions (MTJs). According to the company, their sensors exhibit excellent performance, and they outperform traditional Hall Effect devices with regard to size, power, sensitivity, accuracy and resolution.

In June 2011 Plures Technologies (which holds 95% in AMS) announced a merger with publicly traded CMSF Corporation.


Crocus is an early stage startup, headquartered in Grenoble (France) with operations in the Paris area and in Silicon Valley.

Crocus mission is to become the leading supplier of products and technologies to the MRAM market. The MRAM technology that is the foundation on which Crocus is built was developed in the Grenoble-based Spintec research center and Crocus has formal joint development programs with Spintec and other leading European laboratories.

In June 2006, Crocus raised $17 million.


EvbEverSpin was spun-off Freescale in June 2008, to handle Freescale's MRAM development, and is now an independent company. EverSpin is the world's first and only MRAM producing company, offering MRAM and STT-MRAM chips.


Freescale Semiconductor (formerly Motorola Semi) is a leading global semiconductor company focused on providing embedded processing and connectivity products to large, high-growth markets. Freescale is one of the pioneers of the MRAM industry.

In July 2006, Freescale became the first company to offer commercial MRAM modules (4 Mbit,25$). IP issues with NVE are still open.

Grandis, established in 2002 and headquartered in Silicon Valley, California, develops Spin Torque Transfer based RAM technology (STT-MRAM). STT-RAMTM is a "second generation" magnetic random access memory (MRAM) which solves the writing current scaling problem for conventional MRAM.

In November 2002, Grandis announced a collaboration with Renesas, and in April 2008 they extended this collaboration. They have also announced a licensing deal with Hynix.


Established in 1968, Intel is the world's leading chip maker. Intel is researching Spintronics, and is supporting several universites in their Spintronics research (In 2006, Intel gave 12M$ in research funds and equipment to several Californian universities).

Intel trades in the Nasdaq (ticker is INTC).

Micro Magnetics

Micro Magnetics aims to advance commercial applications of spintronics and provides innovative solutions, products, and services in the areas of magnetic sensing and semiconductor metrology.

Its magnetic current imaging system, the Circuit Scan 1000, is a high-resolution magnetic microscope which provides current density images of operating integrated circuits (ICs). This product family has found utility for failure analysis, fault isolation, and yield enhancement of ICs.

The SpinTJ Series magnetic field sensors are based on next-generation magnetic tunnel junction technology (a.k.a. MTJ or TMR) that offer excellent magnetic sensing capabilities. The SpinTJ sensors feature linear and bipolar response, superior field sensitivity, low noise, low power consumption, and small size. These sensors can also withstand extreme environmental conditions. The SpinTJ Series magnetic sensors have been used in a number of cutting-edge industrial and research applications, including semiconductor failure analysis, compassing and navigation applications, biomagnetic sensing, basic and applied research in magnetism and currency/media validation.


Founded in 2021 as a joint spinout from the University of Glasgow and the University of Edinburgh, Neuranics develops magnetic sensors integrated with semiconductor technology for health, fitness, and metaverse applications.

Neuranics’s patented technology uses scalable spintronics sensors powered by semiconductors to detect tiny magnetic signals from organs in the body – for example the heart and muscles of the arms, which the company says could transform the current shortcomings of health monitoring devices and human-machine interfaces.
