Crossbar is a startup company founded in 2010, and based in California, USA. Crossbar develops a class of non-volatile resistive random-access memory (RRAM) technology.[1] Crossbar RRAM memory allows the ability to deliver up to a terabyte (TB) of storage on a single chip the size of a postage stamp, with very low power, very high performance and compatibility with standard CMOS semiconductor manufacturing processes.[2]


Crossbar was founded in 2010, by George Minassian, Ph.D., Hagop Nazarian, and Prof. Wei Lu.[3] As part of the University of Michigan Tech Transfer program, in 2010, Crossbar licensed the RRAM technology and is the exclusive holder of resistive RAM (RRAM) patents from the University of Michigan.[4] Crossbar has filed 100 unique patents, with 30 already issued, relating to the development, commercialization and manufacturing of RRAM technology.[5]

In August 2013, Crossbar emerged from stealth-mode and announced the development of a working Crossbar memory array at a commercial fabrication. Crossbar's RRAM technology is said to be able to deliver 20× faster write performance; 20× lower power consumption and 10× the endurance at half the die size, compared to best-in-class NAND Flash memory. Since it is CMOS-compatible, it can be easily integrated into existing fabs and processes without any special equipment or materials.[6]

Crossbar has received a total of $25 million in funding from Artiman Ventures, Kleiner Perkins Caufield and Byers, Northern Light Venture Capital and the Michigan Investment in New Technology Startups (MINTS) program.[7]


Crossbar primarily sells to original equipment manufacturers (OEMs) and system on a chip (SOC) developers of consumer, enterprise, mobile, industrial and connected device products.[8]
