Norman, Robert H.

Biographical Notes

Robert (Bob) H. Norman graduated from Oklahoma A&M University in 1954 with a B.S. in electronic engineering and math. In his undergraduate year he worked for the Sperry Gyroscope Advanced Weapon Systems Department on the application of transistors to computer design where he first conceived the idea of using transistors for memory storage. He joined Sperry full time in 1957. Fairchild co-founder Vic Grinich hired Norman to head up the device evaluation section in 1959 where he proposed and designed the DCTL circuit configuration for Micrologic the first planar IC family. He also developed and earned a patent on an early IC memory invention. Norman co-founded two pioneering MOS companies, General Microelectronics in 1963 and Nortec Electronics in 1968 and served as VP Engineering at American Microsystems Inc (AMI), Cupertino, California.
