Numonyx

Numonyx was a semiconductor company founded in 2008 as a joint venture of Intel Corporation, STMicroelectronics and the private equity firm Francisco Partners, combining the flash memory divisions of Intel and STMicroelectronics into an independent entity. Headquartered in Rolle, Switzerland, it designed and manufactured integrated NOR, NAND and Phase Change non-volatile memory solutions for consumer and industrial devices.

Its portfolio covered three memory technologies. NOR Flash products served devices such as cellular phones, MP3 players, digital cameras and computers; in 2009 the company held a 34.6% share of the global NOR flash market, making it the largest vendor in that segment. NAND Flash products were aimed at high-tech and consumer equipment, while Phase Change Memory (PCM) extended the company's non-volatile memory range.

Operations spanned five countries - the United States, Israel, Singapore, China and Italy - alongside the Swiss headquarters, reflecting a footprint in both chip design and manufacturing. Engineering work concentrated on flash memory, non-volatile memory, NOR and NAND technologies, phase change memory and semiconductor design and manufacturing, with applications across semiconductors, consumer electronics, mobile devices, computing, digital imaging and industrial electronics.

Numonyx existed as an independent company from its founding on March 31st 2008 until February 9th 2010, when it was acquired by Micron Technology in a transaction valued at approximately $1.27 billion.
