Rexchip Electronics Corporation was established on November 10, 2006, as a 12" DRAM manufacturing joint venture between Taiwan's Powerchip Technology Corporation (Powerchip) and Japan's Elpida Memory, Inc.  Both Powerchip and Elpida will be providing several key management positions in order to support operations. Rexchip, combining Elpida's advanced R&D strength together with Taiwan's manufacturing efficiency will specialize in the production of high density/high performance DRAM (Dynamic Random Access Memory).

Rexchip's first 12" fabrication facility (Fab R1) began 70nm equipment installation in May of 2007 and in the first half of 2008, full capacity will reach 70,000 wafers per month. Rexchip plans to construct a total four 12" DRAM fabs in Central Taiwan Science Park, with a maximum capacity of 240,000 wafers per month and an investment of over 450 Billion NTD. This will establish as the largest scale foreign joint investment project in Taiwan and creating the world's largest 12" DRAM manufacturing base.
