ROBERT H. DENNARD

INVENTOR RANDOM ACCESS MEMORY (RAM)

Robert H. Dennard was born in Terrell, Texas, USA on September 5, 1932, Robert Dennard, grew up in rural Texas and started school at a one-roof school in the countryside, He told me that he was always looking for a better way to do more things fast for such a quick way of cutting firewood for the stove.

After graduating from high school, Robert Dennard went to college at Southern Methodist University in Electrical Engineering. He received a B.S. and M.S from there in 1954 and 1956, then continued his doctoral studies at the Carnegie Institute of Technology in Pittsburgh, Pennsylvania which later earned his Ph.D. in 1958. His professional career was then spent as a researcher for International Business Machines (IBM). Curiosity and making things simpler then brought it up for improvement to IBM, where it developed a dynamic one-transistor random access (DRAM) memory. At IBM, he also developed a significant theory on the scale of electronic devices, which has been a driving force in microelectronics. For this achievement, Dennard was the recipient of the Lemelson-MIT Lifetime Achievement Award of $ 100,000 in 2005.

In 1966 Dennard was a member of the IBM team doing research on a six-cell memory transistor, and he thought there should be a simple method to build memory in this technology. The solution evolved as a single field effect transistor that reads and writes information stored as an electrical charge on a capacitor, now known as a DRAM cell. DRAM was later patented in 1968. Dennard is also among the first to recognize the tremendous potential of downsizing the MOSFET. The scaling theory he and his colleagues formulated in 1974 basically observed that the MOSFET would continue to function as a controlled voltage switch while all key figures such as layout service density, operating speed, and energy efficiency would increase provided geometric, voltage, and doping dimensions consistent concentrations of scaly as to maintain the same electric field. This property underlies Moore's Law discovered by Robert Moore Founder of Intel and the evolution of microelectronics over the past few decades.

From Here then RAM or Random Access Memory begin to be developed. Random Access Memory (RAM) patented in 1968. RAM (Random Access Memory) is called memory on a PC, actually referring to RAM (Random Access Memory). Computer needs RAM to store data and instructions needed to complete a command (task). Data or instructions that are dedicated specifically for storing data that is not contained from RAM. The special section on this dedicated dedicated hard drive is referred to as virtual memory. Paging file or also known as swapfile on Windows operating system is one example of virtual memory.
