Woburn semiconductor company Nantero gets $32M in funding

Nantero Inc., a Woburn semiconductor company, has raised $31.5 million in new equity funding out of a $41.5 million proposed offering, according to a recently regulatory filing.

The Feb. 3 filing lists 23 investors in total. Some of those listing on the filing include O.B. Bilous, a former IBM executive; Margaret Seif, general counsel at Analog Devices; Dave Fachetti, managing director at Globespan Capital Partners; and Bruce Sachs, a general partner with Charles River Venture.

The company has previously raised money from such investors as Globespan Capital Partners, Charles River Ventures and Draper Fisher Jurvetson.

Nantero uses carbon nanotubes for the development of semiconductor devices including memory, logic, and other products. The company's focus has been to commercialize a product that will replace all current forms of memory including DRAM (dynamic-random access memory), SRAM (static random-access memory) and flash memory with its nonvolatile Random Access Memory or NRAM. The NRAM would replace the memory in a variety of devices including cellphones, digital cameras and tablets.

The company, founded in 2001, last raised $10 million in 2012 and has raised $74 million in total funding.
