Crossbar is a company based in Santa Clara, California.[1] Crossbar develops a class of non-volatile resistive random-access memory (RRAM) technology.[2] The company in 2013 announced its goal was a terabyte of storage on a single integrated circuit, compatible with standard CMOS semiconductor manufacturing processes.[3]


Crossbar was founded in 2010, by George Minassian, Hagop Nazarian, and Wei Lu.[1][4] As part of the University of Michigan Tech Transfer program, in 2010, Crossbar licensed resistive RAM (RRAM) patents from the University of Michigan.[5] Crossbar filed patents relating to the development, commercialization and manufacturing of RRAM technology.[6]

In August 2013, Crossbar emerged from stealth mode and announced the development of a memory array at a commercial semiconductor device fabrication facility. It was said to deliver faster write performance; lower power consumption and more endurance at half the die size, compared to NAND flash memory. Since it is CMOS-compatible, it can be fabricated without special equipment or materials.[7]

Crossbar received $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 in 2012.[8] Another funding round of about $35 million was announced in September 2015, with investors from China and Hong Kong.[9]

Crossbar primarily markets to original equipment manufacturers (OEMs) and system on a chip (SOC) developers of consumer, enterprise, mobile, industrial and Internet of things products.[10] In early 2017, the company announced samples were available from Semiconductor Manufacturing International Corporation.[11]
