Biography Of Robert Dennard. In a computer (PC) or laptop, one of the hardware (hardware) a very important role in the performance and the performance of the computer is Memory or RAM (Random Access Memory), RAM or Memory is a device for storing data that is accessed by the Processor, the inventor of the RAM (Random Access Memory) Computer is Robert Dennard patented in 1968. Robert h. Dennard was born in Terrell, Texas, USA on September 5, 1932, Robert Dennard, grew up in rural Texas and started school at school one stop dipedesaan, she tells that she is always looking for better ways to do things faster as a quick way to cut firewood for the stove.After finishing secondary education, Robert Dennard later continued his studies with admission in College at Southern Methodist University in the Department of electrical engineering, He received his B.S. and m. S from there in 1954 and 1956, and then continued his studies at the Carnegie Institute of technology Doktoralnya in Pittsburgh, Pennsylvania who later earned her Ph.d in 1958. then spent his professional career as a researcher for International Business Machines (IBM). Curiosity and make things simpler then bring it for repair to IBM, where he developed a one-transistor memory dynamic random access (DRAM). At IBM, he also developed the theory of a significant scale electronic devices, which have become the driving force in microelectronics. For this achievement, the award recipient is Dennard Lemelson-MIT Lifetime Achievement $100,000 in 2005.
Robert Dennard
In 1966 Dennard is a member of the IBM research team at six-transistor memory cell, and he thought there should be a simple method to build memory in this technology. The solution is developed as a single field effect transistors that do the reading and writing of information stored as electric charge on a capacitor, now known as DRAM cells. Then in the DRAM patented in 1968.0. Dennard also included the first person to recognize the tremendous potential of downsizing MOSFETs. Scaling theory he and his colleagues formulated in 1974 essentially observed that MOSFETS would continue to function as a voltage-controlled switches while all key figures such as density layout services, operating speed, and energy efficiency will improve provided geometric dimensions, voltage, and a consistent concentration doping scaly like to maintain the same electric field. This property underlies Moore's law discovered by Robert Moore Intel Co-founder and evolution of microelectronics over the last few decades.
From this then RAM or Random Access Memory began to be developed, the RAM (Random Access Memory) is called the memory on the PC, actually refers to a RAM (Random Access Memory). a computer needs RAM to store data and instructions needed to complete an order (task). Data or instructions are dedicated specifically to store data cached from RAM. Special section on special dedicated hard disk is referred to as virtual memory. Paging files or also known as the swapfile on a Windows operating system is one example of virtual memory.
If the paging file is often accessed, it will be a very significant decrease PC performance. As lustrasi, CPU only takes 200 ns (nano second) to access data in RAM. Whereas to access virtual memory on a hard disk, CPU going 12 million takes about ns. Or the comparison takes the CPU to access the paging files on the hard drive of approximately 60,000 times longer than if the CPU accesses data from RAM. In addition to the PC performance is noticeably slow down dramatically, there is still another sign. Such as excessive hard disk access. Even when you are not ordered a new process. Like opening a file, perform the save data, or similar things.
The hard drive continues to work, because the CPU requires a paging file of the data stored in it. This did not always happen. While loading load the PC is still low, the memory can still accommodate the data and instruction that is active. When the PC load full, and loading the data and instructions more, memory starts to run out of the place. And if this is indeed the case that on your PC, it can be used as one of the benchmarks that the system you need larger RAM capacity. After the invention of DRAM by Robert Dennard RAM Types a few years later continue to be developed so that the process becomes faster.
