奇梦达公司（Qimonda AG）是一家在2006年5月1日由英飞凌科技公司分拆而成的新内存公司，为全球第二大的DRAM公司，300mm晶圆工业的领导者和个人电脑及服务器DRAM产品市场最大的供应商之一。

Qimonda奇梦达全球拥有约12,000名雇员，其中包括1,800名研究开发人员；于三个洲拥有五个300mm晶圆生产基地，共营运了五个主要的研究开发设施，其中包括在德累斯顿的领先研究开发中心。Qimonda奇梦达从前强调于个人电脑与服务器产品，现时则集中于使用其省电式深沟电容技术的图像、移动设备与消费者应用产品。2006年8月9日Qimonda奇梦达的股份于纽约证券交易所以股票代号QI发行。

Qimonda奇梦达的业务领域主要集中在DRAM内存领域。包括电脑主机中的DRAM内存条，电脑显示卡的显存颗粒，消费级DRAM内存，移动存储装置中的高速DRAM缓存。另外还有闪存存储芯片。另外家用游戏主机方面，Qimonda奇梦达也有所涉及，例如，任天堂Wii游戏机使用奇梦达GDDR3图形内存。

Qimonda奇梦达在中国涉及的领域包括：研发与设计；市场与销售以及生产等各领域。Qimonda奇梦达将主要进行300mm晶圆生产，提供PC及服务器市场的 DRAM 产品。Qimonda奇梦达还希望成功将产品延伸到图形，移动通讯和由低功率沟槽技术引导的消费类领域。Qimonda奇梦达在苏州设有生产基地和 IT 研发中心，在西安设有产品研发中心，在上海设有销售中心，在北京，深圳设有销售分公司

Qimonda奇梦达产业规模在存储行业居全球第三，尤以芯片的研发能力见长，最重要的两大研发中心分别是慕尼黑研发中心和中国研发中心（位于西安高新区）。受金融危机影响，Qimonda奇梦达于2019年初申请破产保护，浪潮集团抓住机会，打败日本、美国的竞争对手，以3000万元的超低资金并购上亿元的设备和技术。

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). 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.

At its height in 2007, Qimonda employed approximately 13,500 personnel worldwide, from whom 1,800 were employed in R&D with access to four 300 mm manufacturing sites and operating six major R&D facilities, and included a chip packaging complex in Vila do Conde, Portugal, and its lead R&D center in Dresden, Germany, in total covering three continents. During this time, and on into September 2008, the price of DRAM continued to decline due to market oversupply, resulting in significant corporate financial losses throughout 2008.
