Qimonda AG was a leading memory semiconductor manufacturer, spun off from Infineon Technologies in 2006. Headquartered in Munich, Germany, the company specialized in producing dynamic random-access memory (DRAM) products for applications in PCs, servers, and graphics cards. At its peak, Qimonda was among the top DRAM suppliers globally, known for its advanced trench technology and R&D innovations. However, due to severe industry downturns, price pressures, and financial difficulties, the company filed for insolvency in 2009. Its assets were subsequently liquidated, marking the end of a once-prominent European chipmaker. Qimonda's technological contributions continue to influence the semiconductor field.
