Integral Solutions Int’l (ISI)

ISI logoIntegral Solutions Int’l (ISI) is a privately held US-based company that supplies Quasi Static Testers for characterizing Magneto-Resistive type heads.

ISI's product suite includes QST testers for every stage of manufacturing. ISI says that about 85% of the entire head production for the HDD industry is being tested on ISI's equipment.


Intel is the world largest chip maker, and also manufactures networking, memory and communications products.

Intel is researching several next-generation memory technologies including MRAM memory, although it currently seems focused on its 3D XPoint memory.

Leuven Instruments

Leuven Instruments logoJiangsu Leuven Instruments was established in 2017 by Leuven Instruments of Belgium and the Institute of Microelectronics of the Chinese Academy of Sciences. The company develops and produces semiconductor etching equipment and process development equipment, especially for magnetic material etching technology.

For the MRAM industry, Leuven Instruments offers the LMEC-200 Magnetic-layer Etching Cluster system that integrates ICP etching, IBE etching, in-situ protection and more. In April 2020 the company closed its Series B funding round, raising $14.1 million from several investment firms.


MagOasis logoMagOasis, founded in 2006, provides design/analysis software applications and services for the information-storage and allied industries covering magnetic recoding heads, MRAM, Magnetic nanostructures devices, graphene, sensors and more.

MagOasis' MRAM-related software, Spin-Valve Bench (SVB), is a micromagnetic software for the design and analysis of advanced multi-layer spintronic devices. These include modern MRAM cells for non-volatile microelectronic applications, nanowires and magnetoresistive read-head sensors for ultra-high density recording applications.


Micromem (OTCMKTS:MMTIF) develops magnetic-based sensors, based on spintronics technologies.

The company used to develop MRAM devices, but it seems that it is now entirely focused on its sensors business.


MicroSense (previously known as ADE Technologies) designs precision capacitive position sensors and vibrating sample magnetometers for magnetic measurement.

For the MRAM market, MicoSense offers the Polar Kerr System which provides 300-mm non-contact magnetic property metrology system for perpendicular MRAM. The system utilizes the polar Magneto-Optical Kerr Effect (MOKE) to characterize the magnetic properties of multi-layer wafers used in the development and manufacturing of perpendicular MRAM.


MRAM-Info, launched in 2004 and based in Israel, is a knowledge hub and web publication focused on MRAM technologies.

MRAM-Info provides news, resources and services to the MRAM industry and is considered to be the leading MRAM publication.

Northern lights

Northern Lights Semiconductor Corporation was established in 2003 in the US to design and manufacture high-density EMRAM (ElectroMagnetoresistive RAM) chips.

NLSC developed a family of parallel and serial standalone EMRAM devices and reported on customers in a variety of industries and markets including computer, computer peripheral, communication, consumer and industrial markets. The company did not post any update since 2005 and it is not clear if it is still in business.


Numem logoNumem (previously NVMEngines) is a US-based early stage company that develops high-performance, low-power embedded STT-MRAM IP cores for the IoT, micro-controller and automotive markets. Numem says its memory enables a 2-3x smaller memory area and 20x to 50x lower standby power compared to SRAM.

The company also develops design automation tools to optimize Power/Performance/Area (applicable for MRAM and ReRAM technologies).


QuantumWise logoQuantumWise is a provider of software solutions for development of nanotechnology. QuantumWise bought the assets of Atomistix after it went bankrupt in January 2009. The company is working in close collaboration with the Nano-Science Center at the Niels Bohr Institute of Copenhagen University. QuantumWise was acquired by Synopsys in 2017.

QuantumWise is offering a system of integrated software modules that can accurately calculate properties associated with electron distribution and transport. The software can accurately simulate experiments with spin-dependent transport, as encountered in Tunneling Magnetoresistance (TMR) technologies and Magnetic Nanowires. The software is called "Atomistix Toolkit" (or ATK).


Rangduru logoEstablished in 2011 in the US, Rangduru developed an MRAM memory structure called DX MRAM that uses a cell structure that is twice as dense as current MRAM structures.

Rangduru operates in a fabless model and develops both discrete MRAM chips and embedded MRAM technologies.


Samsung logoSamsung is a large Korean conglomerate focusing on electronics, displays (both LCDs and OLEDs) and semiconductors. Samsung is a leading memory producer and is researching several next-generation memory technologies, including RRAM and MRAM.

Samsung collaborates with several companies on STT-MRAM technologies, including Hynix and IBM.In April 2016 Samsung's semiconductor unit manager said that Samsung will be ready with MRAM chips soon.

Singulus technologies

Singulus technologies (ETR:SNG) is a German-based company that focuses on manufacturing equipment for optical discs. Singulus' products range from mastering and injection molding to replication lines.

Singulus is offering its TIMARIS machine for Thin Film read/write heads (up to 300mm wafers), used in MRAM production, and has already sold several systems (we know that Grandis and Crocus have acquired at least one of these systems each).

Spin Memory

Spin Memory logoSpin Memory (previously Spin Transfer Technologies), established by established by NYU and Allied Minds, is developing STT-MRAM devices based on its Orthogonal Spin Transfer MRAM (OST-MRAM) technology.

In November 2018 Spin Memory licensed its Endurance Engine MRAM technology to Arm. In 2016 Spin Memory produced 20nm OST-MRAM MTJs, and said it is preparing to start delivering samples to select customers. In 2015 the company raised $70 million (in addition to $36 million raised in 2012) and in November 2018 the company announced its $52 million Series B funding round.
