Crossbar has raised $20.5 million from undisclosed investors for its memory storage technology that could be a possible successor to flash. According to a Form D filed with the Securities and Exchange Commission, Crossbar has an intent to raise $21 million.

Crossbar has previous investments from Correlation Ventures, with additional funding from Artiman Ventures, Kleiner Perkins Caufield & Byers, and Northern Light Venture Capital. Crossbar provides of solutions for the global memory storage industry.

“Crossbar” is a term used to describe a new highly dense architecture for mobile devices. The mobile market faces a barrier with traditional, non-volatile flash storage. Device makers can only do so much to make the mobile technology smaller while at the same time enlarging capacity.

According to nanoRev, traditional processor architectures segregate the memory circuitry from the logic circuitry. Crossbar architecture melds the two to make it more like how our brains function. :

Crossbar architectures have been applied to the creation of programmable logic devices in the past few decades but only recently have been proposed at the nanometer level by companies such as Hewlett-Packard (using nanowires) and Nantero (using nanotubes). One key advantages of using crossbar architectures for memory is that they would be able to provide resources useful for both reconfigurable computing and for data storage. This is in strict contrast to conventional processor architectures which segregate the memory circuitry from the logic circuitry and is closer to the type of organization found in the brain which integrates signal processing and memory storage.

I reached out to Crossbar for comment and will update if they respond.
