On April 14, 2004, Dr. Chang-Gyu Hwang presented his talk, "The Role of Semiconductors in the Next IT Era," at the Massachusetts Room of the Mullins Center, University of Massachusetts Amherst.

Abstract: As we enter the nanotechnology era, a big shift in paradigm comes to the semiconductor industry. The traditional computer industry for dynamic RAM is expected to mature its memory-bit consumption with a relatively low growth rate. Meanwhile, memory consumption and high-density memory usage in mobile handsets and digital consumer applications will grow very fast. For these new applications, NAND Flash memory will be the key enabling technology, and its easy scaling and multibit/cell capabilities require a new memory growth model. The well-known Moore’s law still holds for most cases after the quarter-century history of the integrated circuit industry. However, the paradigm shift in the memory industry requires a new memory growth model: “a twofold increase per year in memory density.” The lecture will cover some details of recent semiconductor technologies, application trends, the proposed new memory growth model and will also focus on the synergy effect of memory and system large-scale integration LSI products like MCP, SIP and SoC.


Dr. Hwang is an alumnus of UMass Amherst (EE '85) and has been with Samsung Electronics since 1989; his responsibilities include research, development, and manufacturing of all semiconductors, OMS (Optical Media Solution) and HDD (Hard Disk Drive) products.

Dr. Hwang was selected as “One of the 25 Stars of Asia” by BusinessWeek in 2003 and was listed as one of the top three contributors in science and technology in “Top Fifty Contributors to Korean History for the Last Fifty Years” by JoongAng Newspaper in Korea in 1995.

He has authored more than 50 technical papers in international journals and conferences and holds several international patents related to semiconductor design and process. He was elected an IEEE fellow in 2002 and serves actively as a senior member of the IEEE Electron Device Society and the Circuit and System Society. His paper titled “Nanotechnology Enables a New Memory Growth Model” appeared on “Proceedings of the IEEE” 2003 November publication.

Each year the University of Massachusetts Amherst Alumni Association recognizes members of the UMass Amherst family for outstanding personal or professional success. On Thursday, April 15, Dr. Hwang will be presented with a 2004 Distinguished Alumnus Award at a special ceremony at the State House in Boston. The award will honor Dr. Hwang's prominent role in international business and his distinguished service to the technology industry.
