Robert Heath Dennard(September 5, 1932 – April 23, 2024) was an Americanelectrical engineerand inventor.[1]
Biography[edit]
Dennard was born in Terrell, Texas. He received his B.S. and M.S. degrees in Electrical Engineering fromSouthern Methodist University,Dallas,in 1954 and 1956, respectively. He earned a Ph.D. fromCarnegie Institute of TechnologyinPittsburgh, Pennsylvania,in 1958. His professional career was spent as a researcher forInternational Business Machines.[1]
In 1966 he invented the one transistor memory cell consisting of a transistor and a capacitor for which a patent[2]was issued in 1968. It became the basis for today'sdynamic random-access memory(DRAM) and almost all other memory types such as SRAM and FLASH memory. Dennard was also among the first to recognize the tremendous potential of downsizingMOSFETs.Thescaling theoryhe and his colleagues formulated in 1974 postulated that MOSFETs continue to function as voltage-controlled switches while all key figures of merit such as layout density, operating speed, and energy efficiency improve – provided geometric dimensions, voltages, and doping concentrations are consistently scaled to maintain the same electric field. This property underlies the achievement ofMoore's Lawand the evolution of microelectronics over the last few decades.[1]
In 1984, Dennard was elected a member of theNational Academy of Engineeringfor pioneering work in FET technology, including invention of the one transistor dynamic RAM and contributions to scaling theory.
Dennard died on April 23, 2024, at the age of 91.[3][1]
