Imec's resistive RAM research shows momentum in 2012 VLSI Technology Symposium papers

Leuven, (PresseBox) - At this year's Symposia on VLSI Technology and VLSI Circuits (June 12-15, 2012 - Honolulu, USA,), imec and its partners will present 10 papers on memory and logic scaling technology and circuits. With 4 RRAM (resistive RAM) papers accepted, the VLSI reviewing committee endorses the value of imec's R&D program on emerging memory devices. And 5 papers will address logic device scaling and characterization for next-generation CMOS technologies. This confirms imec's leading global position as R&D center in CMOS scaling technologies. Besides, imec and its partners will also present one paper on an innovative VLSI circuit for electro-encephalogram (EEG) and contact-impedance acquisition for dry-electrodes.

Gosia Jurczak, Director of imec's emerging memory device program: "In 2008, imec started with research activities on RRAM in order to explore solutions to overcome the scaling limitations of conventional Flash memory cells. We are very pleased with this year's high appreciation of imec's RRAM research papers at the VLSI Technology Symposium. This, and, the fact that since 2008 all major memory players joined our research program on emerging memory technologies, proves the value of our RRAM research to the global industry."

Aaron Thean, Director of imec's logic device program: "We are delighted that 5 imec papers on advanced logic device process, design, and characterization have been accepted for this year's Symposium on VLSI technology. It is definitely an affirmation of the active device research work at imec to extend Moore's Law scaling."
