TitleGreene patent notebook (#454)
DescriptionDescribes testing of devices for use in ferrite core memory systems. Evaluation of core output vs. drive, detector circuits, and core switching inductance. Compares core vs. thin-film vs. semiconductor technologies for storage. A demonstration system for bipolar 256-bit IC memory chips (possibly a predecessor to the Illiac IV project) and a proposed bipolar memory cell design (p. 142). .
AuthorGreene, Frank S., Jr.
Biographical NotesFrank S. Greene attended Washington University in St. Louis where he obtained a B.S.E.E. He earned an M.S. in electrical engineering at Purdue University and a Ph.D. at Santa Clara University in 1970. He joined the Fairchild Memory Products Division as a junior engineer in Harley Perkins’ Ferrite Core Memory Group in 1965. By 1968 this activity was closed and Greene worked in a Flat-Wire Memory section managed by C. Bittmann in the Physics Department. In 1970-71 he worked with Wendell Sander on the Illiac IV semiconductor memory system project. In the early1970s, he co-founded software and computer service companies Technology Development Corp. and ZeroOne Systems Inc. Greene was among the first black students to attend college at Washington University and an early African-American engineer in Silicon Valley. He founded NewVista Capital, a venture capital firm with a special focus on minority and female-headed firms.
