Jiangsu Lemote Tech Co., Ltd or Lemote (Chinese: 龙梦; pinyin: lóng mèng; literally "Dragon Dream") is a computer company established as a joint venture between the Jiangsu Menglan Group and the Chinese Institute of Computing Technology, involved in computer hardware and software products, services, and projects.

In June 2006, the Jiangsu Menglan Group began a joint venture with the Institute of Computing Technology of the Chinese Academy of Sciences. The venture was named Jiangsu Lemote Tech Co., Ltd. The predecessor organization was the Center of Technology Research and Development of Jiangsu Loongson CPU Industrialization Base.
A computer was announced by Zhang Fuxin, an ICT engineer, who said the purpose of this project was to "provide everyone with a personal computer". The device is intended for low income groups and rural area students.
Lemote, with partners, provides integrated circuit design services, helps develop the Loongson series of MIPS-based RISC microprocessors, and builds small form factor computers including network computers and netbooks.
Loongson (Chinese: 龙芯; pinyin: lóngxīn, academic name: Godson, also called Dragon chip) is a range of MIPS instruction set RISC processors used in all Lemote products. Some Loongsons include on-chip circuits to help resist buffer overflow attacks.[clarification needed]
The Yeeloong netbook computer is intended to be built on free software from the BIOS upwards, and for this reason is used and recommended by Richard Stallman as of September 2008 and January 23, 2010
Lemote also collaborated in the development of the Gdium netbook which uses its Loongson MIPS processor.
Loongson 3A laptop
Loongson insiders revealed a new model based on the Loongson 3A quad-core laptop has been developed and was expected to launch in August 2011. With a similar design to the MacBook Pro from Apple Inc., it will carry a GNU/Linux operating system by default.
In September 2011, Lemote announced the Yeeloong-8133 13.3" laptop featuring 900 MHz, quad-core Loongson-3A/2GQ CPU.
