Qimonda AG was a memory company split out of Infineon Technologies (itself a spun off business unit of Siemens AG) on 1 May 2006, to form at the time the second largest DRAM company worldwide, according to the industry research firm Gartner Dataquest. It is now a patent licensing firm. Headquartered in Munich, Germany, Qimonda was a 300 mm manufacturer, and was one of the top suppliers of DRAM products for the PC and server markets. Infineon still controls a 77.5% stake, which it has written down (2008).
