Dr. Perumal Ratnam has worked in various areas of semiconductor technology (CMOS/BiCMOS/SOI/HV) for the last fifteen years. Dr. Ratnam has worked with various foundries such as UMC, TSMC, Chartered Semiconductor, Rohm (Japan) and Tower Semiconductor, and has wide experience in dealing with foundry technology issues for LOGIC and Memory products at 0.25, 0.18, 0.15, and 0.13 levels. Dr. Ratnam was instrumental in developing Flash memory products at Alliance Semiconductor and bringing their 4Mb/8Mb products to production.

He also came up with the Ultra Low Power Design Techniques for Wireless Products that are currently in use at Alliance. At Alliance Dr. Ratnam manages several people, both on-site and off-site, improving assembly and testing procedures, raising yields and bringing new products to production.In addition to serving as the foundry interface at alliance Semiconductor, Dr. Ratnam has many other technical achievements.

Dr. Ratnam has published more than twenty-five (25) papers in various journals and conferences, such as IEEE Transactions, IEDM and Electronics Letters, etc. He has published numerous reports and communications related to technology development and product development of memory products, and has been granted six (6) patents, with four (4) additional patents pending. Most of Dr. Ratnam's research/development work has been on Technology Developments for CMOS, BiCMOS, SOI and HV devices for switch mode power supply.

Dr. Ratnam is currently involved in bringing related Hyper Transport and high speed 16/32Mb SRAMs to production at two different offshore foundries at 0.15/0.13um.
