Fascinating facts about Robert H. Dennard inventor of Dynamic Random Access Memory in 1967. ROBERT DENNARD
AT A GLANCE:
Robert Heath Dennard invented the one-transistor
dynamic random access memory DRAM in 1967. It has become the standard for the RAM industry and enabled the microcomputer revolution because prior to his invention, computers were too large and heavy to be installed in homes or placed on desktops. Before the early 1970s, computers required separate storage space and dedicated air conditioning units to keep them cool.

IBM Fellow
Robert Dennard was a young Texas-bred scientist who thought he knew where he was headed when he arrived at IBM in 1958. He figured he'd "go to IBM and learn a lot of good stuff, and then maybe go out to a smaller company and work my way up. I figured I'd spend about three years." A short chuckle sets up the obvious punch line: "That was 38 years ago."
