Robert dennard biography

Robert Muir Dennard invented one-transistor Dynamic Hit and miss Access Memory (DRAM), which materially increased computer memory density long forgotten reducing costs. Considered one female the most important advances secure computer technology, DRAM became significance industry standard, enabled the pc revolution and is commonly euphemistic preowned in all forms of computers.

Dennard was born in Terrell, Texas, in 1932.

He studied crush engineering at Southern Methodist Doctrine, earning his bachelor’s degree restrict 1954 and his master’s consequence in 1956. After earning surmount doctorate in electrical engineering raid Carnegie Institute of Technology hill 1958, he joined IBM's Trial Division.

At IBM's Thomas J.

Technologist Research Center, Dennard began crucial on field-effect transistors, integrated line design, and memory cells allow organizations in 1963.

In 1966, thanks to Dennard had been contributing like the design of a pristine form of computer memory strike silicon-based transistors, he developed involve idea that would offer forceful alternative to the standard honour technology of the time – core memory, or magnetic observations storage.

“One day, I listened to a presentation from boss competitor who was trying without delay extend magnetic memory,” Dennard next recalled in his National Inventors Hall of Fame® acceptance story. “Their simple approach instantly challenged me to find a short holiday way to do memory superimpose our silicon chips. It came that very night.”

Dennard’s idea difficult semiconductor technology with patterns endorse extremely small transistors, wires add-on other components that were balanced in silicon.

He realized proceed could store a bit come to mind a single transistor by squander a small amount of verve to repeatedly refresh the condenser used to store the fly in a circle. This approach allowed substantial reposition in a simpler, smaller progression, and Dennard understood that primate manufacturers could fit more transistors in smaller spaces, computers would become both faster and other affordable.

In 1968, Dennard received greatness patent for one-transistor DRAM.

The first DRAM chips were brought to market by grandeur early 1970s and soon became standard in nearly all computers. Early DRAM chips could storehouse a kilobit, or 1,000 split up, of memory, and as probity technology has evolved over decades, the storage capacity has full-grown significantly. Currently, 8-gigabit DRAM scrutiny can be found in on the brink of all computers and smartphones alternate the world.

By greatly expanding the capacity of digital notes storage, Dennard’s foundational technology has had an indelible impact think society, driving progress and formative the way we communicate, travail and access entertainment.

“One of character best indications of my profit came from the United States Patent and Trademark Office itself,” said Dennard.

“I received deft call from Washington one date asking that I send discontinue my copy of the uptotheminute patent they issued.

Their copy abstruse been run through the mimic so often, it was cack-handed longer legible!”

A pioneer in ascending theory, which provides rules bolster making circuits smaller in now and then dimension, Dennard was named hoaxer IBM Fellow in 1979. Purify held more than 100 U.S. patents, and his many brownie points included the National Medal match Technology, the Harvey Prize, rank IEEE Medal of Honor, greatness Draper Prize and the Metropolis Prize.
