Infineon was created in 1999 from the semiconductor division of Siemens. The impetus for separating the semiconductor business was the collapse of prices for DRAM computer memory in the late 1990s; in 1998, this division brought Siemens a loss of $674 million. At the time of its creation, Infineon became the world leader in DRAM production, occupying about a third of the world market; this product provided 30% of revenue, the rest came from radio frequency modules (in particular Bluetooth), as well as equipment for wired communications. In 2006, DRAM production was separated into a new company, Qimonda, which filed for bankruptcy three years later. Initially, Infineon became a subsidiary of Siemens, but in 2000 its shares were placed on the Frankfurt and New York stock exchanges, by 2001 Siemens reduced its share to 41.3%.
