Crossbar RRAM Technology: The resistance switching mechanism of Crossbar’s technology is based on the formation of a filament in the silicon-based switching material when a voltage is applied between the two electrodes.

Crossbar Inc., which licensed the technology from U-M in 2010, recently announced it has developed a working "resistive random access memory," or RRAM, prototype in a commercial fabrication facility. That's a major step toward bringing the technology to market.

Smartphones are just one place it could be used. RRAM is a new form of nonvolatile memory that has the potential to replace the flash memory commonly used in tablets, digital cameras and solid-state drives, in addition to mobile phones. Nonvolatile memory stores information even when it's powered down.

Crossbar's RRAM promises up to 1 TB of storage on a chip that performs 20 times faster with 20 times less power and 10 times the endurance of today's best-in-class flash, according to a company statement. That means it could hold roughly 12 times more HD video than today's comparable flash memory, which maxes out before 20 hours. It could store 250,000 songs, compared with today's 16,000.

Crossbar was formed with the help of venture capital firm Kleiner Perkins Caufield and Byers, which led the initial round of funding—their first investment in a U-M startup.

"We continue to be excited about the disruptive potential of Crossbar," said John Denniston, KPCB partner. "The company has made excellent progress since our initial investment and is now poised to bring a much-needed solution to the memory markets.

"It's been a privilege to support Prof. Wei Lu and his team in developing this ground-breaking innovation. And we've been very pleased with the collaboration with Univ. of Michigan—and in particular the Technology Transfer team—all along the way."

Headquartered in Santa Clara, Calif., the company has now raised a total of $25 million, according to a Wall Street Journal report.

"Crossbar's technology can offer higher memory densities and faster speeds at lower prices. I expect it to be available in the embedded memory market first followed by introductions in the consumer and enterprise IT markets," said Wei Lu, the assoc. prof. of electrical engineering and computer science from whom Crossbar licensed the technology. Lu is also chief scientists at Crossbar.

"With our working Crossbar array, we have achieved all the major technical milestones that prove our RRAM technology is easy to manufacture and ready for commercialization," said Crossbar CEO George Minassian. "It's a watershed moment for the nonvolatile memory industry."

Crossbar was the first U-M startup to receive a direct investment from the university through its unique Michigan Investment in New Technology Startups program.
