Everspin Technologies is a public semiconductor company that develops and manufactures magnetic RAM or Magnetoresistive Random Access Memory (MRAM), including stand-alone and embedded MRAM products as well as Spin-torque MRAM (ST-MRAM). MRAM has the performance characteristics similar to standard Random Access Memory (RAM) while also having the persistence of non-volatile memory, meaning that it will not lose its charge or data if power is removed from the system. This characteristic makes MRAM suitable for a large number of embedded applications, such as automotive and industrial where both performance and permanence are required.

The company was formed in June 2008 as a spin out of Freescale Semiconductor. In 2014 Everspin partnered with GLOBALFOUNDRIES for production of in-plane and perpendicular MTJ ST-MRAM on 300mm wafers, utilizing 40nm and 28nm node processes[1].  Everspin it went public with an IPO in October 2016.

Technology[edit]

MRAM uses the magnetism of electron spin to provide fast and enduring non-volatile memory. MRAM stores information in magnetic material that is integrated with silicon circuitry to deliver the speed of RAM with the non-volatility of Flash.[citation needed]

Everspin is considered to be the world's first volume MRAM supplier[17] and established an MRAM intellectual property portfolio of more than 600 active patents and applications, many of which are fundamental and essential for MRAM technologies including MTJ-based products.[citation needed]

Headquartered in Chandler, Arizona, Everspin owns and operates a manufacturing line for its magnetic back-end-of-line wafer processing, using standard CMOS wafers from foundries.[citation needed] Everspin's current MRAM products are based on 180-nm and 130-nm process technology nodes and industry standard packages.[citation needed]

Markets[edit]

Data Center and Storage[edit]

MRAM is used in storage, server and networking applications such as RAID, NAS, SAN and DAS applications, as well as rack and blade servers and routers.[18]

Energy and Infrastructure[edit]

MRAM products have been designed into energy and infrastructure applications such as smart grid, smart meter, solar and wind applications, industrial computing and automation, and casino gaming.[19][20][21]

Automotive and Transportation[edit]

Everspin supplies MRAM products for automotive and transportation applications including power train, brakes, safety, data logging, multimedia, navigation, camera and in-flight computers.[22][23][24][25]

Investors[edit]

Investors include: New Venture Partners, Lux Capital, Sigma Partners, Draper Fisher Jurvetson and Epic Ventures.[citation needed]
