Magnachip to Offer Cost Competitive Compact Standard Cell Library for Low Power Applications

SEOUL, South Korea, Nov. 7, 2011 — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed signal semiconductor products, today announced that it now offers cost competitive compact standard cell libraries targeting low power applications in 0.18um and 0.35um technologies.

The new standard cell library features a smaller cell area and lower operating power by incorporating a compact design architecture. The cell area is reduced by up to 25% and the operating power consumption by a maximum of 60% compared with the use of conventional design libraries. In addition, these new compact standard cell libraries have the advantage of increased speed in addition to leakage and latch up control when compared to previous compact standard cell libraries. Any weakness to latch up is sharply reduced by using a self-well bias contact scheme.

T.J. Lee, Senior Vice President and General Manager of MagnaChip’s Corporate and SMS Engineering commented, “We are very pleased to announce the offering of our competitive compact standard cell library for cost effective and low power applications These cell libraries will provide cost competitiveness and design flexibility to meet the increasing application specific needs of our foundry customers.”
