SANTA CLARA, Calif. and Hsinchu, Taiwan November 30, 2011 - Kilopass Technology Inc., a leading provider of semiconductor logic non-volatile memory (NVM) intellectual property (IP), and United Microelectronics Corporation (UMC) (NYSE: UMC; TWSE: 2303), a leading global semiconductor company, today jointly announced that they have expanded their existing manufacturing license agreement. In addition to the 40nm low-power process in the current agreement, the extension will cover UMC technology processes spanning from 55nm to 130nm. Future plans include UMC's 28nm High-K metal gate (HKMG) and Poly/SiOn processes, based upon customer demand. This technology roadmap supports the companies' mutual customers to achieve leading edge SoCs with Kilopass' XPM^TM, Gusto^TM, and Itera^TM NVM products for a wide range of UMC process nodes.

This agreement broadens UMC's engagement with Kilopass' based on increased customer adoption and the leadership position Kilopass has in embedded logic NVM technology. Kilopass perceives design activity in greater China has increased rapidly, and that UMC's dominance has become a significant factor to Kilopass' continued growth.

"We are pleased to add Kilopass as another member of UMC's circle of strategic partners," said S.C. Chien, Vice President of Customer Engineering & IP Development & design Support at UMC. "We see Kilopass' OTP (One Time Programmable) roadmap, customer adoption, and broad portfolio of unique offerings as convincing factors for an ideal OTP partner for UMC. Their logic NVM solutions will nicely complement UMC's existing embedded NVM portfolio, which includes eFlash, eE²PROM, eMTP, eOTP and eFuse. We look forward to Kilopass continuing the excellent support it has delivered thus far."

"I am very excited that Kilopass has won UMC to our anti-fuse NVM technology," said Charlie Cheng, president and CEO of Kilopass Technology, Inc. "Finally, we have achieved our strategic initiative of covering the broad range of UMC product line so we can be truly successful in greater China, where customers appreciate UMC's focus on best price/performance and customer-first business approach."

The initial partnership started in 2010 with UMC's 40LP process, which is available now. With customer demand increasing for other technology nodes, both companies decided to provide anti-fuse embedded NVM as an off-the-shelf ready product at 130/110/55nm processes with future plans to include HKMG processes.

The agreement will start with the foundry's 55SP (Standard Performance 55-nanometer) process, a sweet spot for several consumer infotainment projects. Both companies expect to start delivering 55SP solutions in Q4, 2011 with the rest of the roadmap delivered in 2012. UMC's 55SP delivers competitive price/performance and turnaround time while Kilopass offers these customers an embedded NVM solution that can provide a broad product range from 4Kb to 4Mb, covering an extensive ecosystem.
