EverSpin was spun off from Freescale in June 2008, to handle Freescale's MRAM development, and is now an independent company. Everspin was the world's first MRAM producer and remains one of the leading ones, offering both MRAM and STT-MRAM chips.
In 2016 Everspin became a public company following a $40 million IPO.
Grandis, established in 2002 and headquartered in Milpitas, California, developed Spin Torque Transfer based RAM technology (STT-MRAM). STT-RAM 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. The company also announced a licensing deal with Hynix.
Grandis was acquired by Samsung in 2011.
Freescale Semiconductor (formerly Motorola Semi) was a global semiconductor company focused on embedded processing and connectivity products. Freescale was one of the pioneers of the MRAM industry.
In July 2006, Freescale became the first company to offer commercial MRAM modules (4 Mbit, $25). In June 2008 it spun off its MRAM business as Everspin, and in 2015 Freescale was acquired by NXP.
Crocus Technology was a spintronics company headquartered in Grenoble (France), with operations in the Paris area and in Silicon Valley.
Crocus set out to become a leading supplier of products and technologies to the MRAM market. The MRAM technology on which Crocus was built was developed in the Grenoble-based Spintec research center, and the company ran formal joint development programs with Spintec and other leading European laboratories. In later years Crocus shifted its focus to TMR magnetic sensors.
In June 2006, Crocus raised $17 million. In October 2023 Crocus Technology was acquired by Allegro MicroSystems for $420 million.
NVE develops and sells devices (Sensors and couplers) using spintronics. NVE is also into MRAM research, and lists Motorola, Cypress and Agilent as licensees.
NVE trades in the NASDAQ (ticker is NVEC). You can follow the latest spintronics news from NVE here.
