SANTA CLARA, Calif. and Hsinchu, Taiwan May 28, 2013 - 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 foundry, today jointly announced that they have signed a technology development agreement. The agreement calls for Kilopass to port its non volatile memory (NVM) Intellectual property (IP) to two of UMC's leading edge 28nm processes: the High-K Metal Gate 28HPM in high demand by portable device system on chip (SoC) manufacturers and the poly gate 28HLP favored by consumer electronics SoC designers.

UMC's 28nm process delivers twice the gate density of 40nm. Its cost-effective 28HLP Poly/SiON process delivers vastly improved performance and power consumption over other 28nm Poly/SiON industry offerings. The process provides a selection of voltage options to accommodate SoC designers differing power supply needs: 1.8v, 2.5V, and 2.5/ 3.3V. The 28HPM High-k/metal gate process provides options for device voltages, memory bit-cells and underdrive/overdrive capabilities to help SoC designers realize substantial gains in performance and battery life.

"We remain dedicated to advanced technology development and timely capacity deployment to serve our customers' needs," said S.C. Chien, Vice President of Customer Engineering & IP Development & design Support at UMC. "To ensure our customers have access to not only UMC's eFlash, eE2PROM, eMTP, eOTP and eFuse, but also the best third-party non-volatile memory IP at the 28nm node, we are happy to continue our partnership with Kilopass to ensure that their variety of anti-fuse NVM IP offerings is available on our 28nm process family."

"We are extremely pleased with the progress of our on-going strategic initiative with UMC," said Charlie Cheng, president and CEO of Kilopass Technology Inc. "Enablement of our NVM IP offerings on UMC's major 28nm nodes is a win for both companies. It provides an expanded IP portfolio in advanced process nodes that UMC can offer its customers. And it broadens Kilopass' reach into mobile device SoCs and consumer electronics SoCs where UMC's 28nm processes have a growing presence and expanding market share."

The initial Kilopass-UMC 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 be proactive to provide anti-fuse embedded NVM as an off-the-shelf ready product at 130/110/55nm processes, which was accomplished in 2012. This latest agreement expands the relationship into the 28nm process node.
