Dr. Mahn-Jick Lim, CEO and President, founded MJL Technology in 1988. MJL's mission is to develop the most reliable, high technology products for the worldwide market, and to provide advanced information technology solutions to customers based on strategic partnerships and MJL's own core technologies. MJL operates two main business lines, the Information Technology Business Department and the Logic Design Business Department. Core technology is developed in the MJL R&D Center, and US based operations are run from MJL America, a wholly owned subsidiary of MJL Technology.

The Information Technology Business Department has been successfully penetrating leading carrier-grade telecommunications service providers with Lark Series 10. Reference sites includes Korea Telecom - the largest land-based telephone carrier in Korea, Shinsegi Telecom - the second largest land-based telephone carrier in Korea. The IT Business Department also has successfully deployed carrier-class, network infrastructure projects throughout Korea, such as the fourth KORNET Expansion Project of Korea Telecom, in which MJL was the primary contractor in 2000. Additionally, MJL designed and built the VoIP Network in Daejeon KRTC.

The Logic Design Business Department encompasses logic design with very high-density PLD devices. During the last decade, MJL has helped primarily large corporations in Korea design and develop logic circuits using PLDs/CPLDs/FPGAs. The designs are mostly for telecommunication-switching equipment including TDX-100, telecommunication base stations for CDMA, various new generation equipment for IMT-2000 (3rd Generation Wireless), broadband equipment, and network equipment. These efforts resulted in MJL capturing the largest PLD-business market share in Korea.

The Component Business Department currently covers network and wireless based chipsets, including analog and embedded systems. This business group, formed in 2001, is also responsible for new technologies and new partnerships.
