Qimonda AG, (pronounced "key-MON-da") 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. Headquartered in Munich, Germany, Qimonda is a 300 mm manufacturer, and is 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). Infineon was on record as having the aim of divesting itself of this stake, with the purpose of becoming a minority stakeholder in 2009. The company has issued 42 million ADR shares, each ADR share representing one ordinary share in Qimonda.
