. Crossbar develops a class of non-volatile resistive random-access memory (RRAM) technology.


History

Crossbar was founded in 2010, by George Minassian, Hagop Nazarian, and Wei Lu. As part of the
University of Michigan The University of Michigan (U-M, U of M, or Michigan) is a public university, public research university in Ann Arbor, Michigan, United States. Founded in 1817, it is the oldest institution of higher education in the state. The University of Mi ...
Tech Transfer program, in 2010, Crossbar licensed resistive RAM (RRAM) patents from the University of Michigan. Crossbar filed patents relating to the development, commercialization and manufacturing of RRAM technology. 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 Flash memory is an Integrated circuit, electronic Non-volatile memory, non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for t ...
. Since it is CMOS-compatible, it can be fabricated without special equipment or materials. 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. Another funding round of about $35 million was announced in September 2015, with investors from China and Hong Kong. Crossbar primarily markets to original equipment manufacturers (OEMs) and
