Contriver of chip of 76 years old of DRAM will win IEEE honorary medal next week

Beijing time on June 19 midday message, according to foreign media coverage, rob spy · ascends IBM researcher of 76 years old accept heart (Robert H. Dennard) will at next week 4 obtain " association of electric electron engineer " (the honorary decoration that IEEE) sends.

The heart that mount offer worked 51 years in IBM, its basically accomplish have two: The scale that the DRAM memory chip that acting 1960 end invents and acting 1970 metaphase publish is academic (Scaling Theory) . Scale theory was elaborated how to narrow ceaselessly dog stairs best buy transistor dimension, development is smaller, faster, cheaper the method of chip. The heart that mount o dog crates large breed ffer says scale theory is mixed rub Er is mensurable " bring out the best in each other " .

If do not have DRAM chip, the case of computer memory will be as similar as current hard dvd discovery disk and jotter batteries. Memory of the heart that mount offer says, acting 1960 end, IBM large scale main computer basically uses magnetism core memory. Magnetism core memory not only easy attaint, the best selling dog crates large and the price costly, rate is slow, but firstly the advantage is to have blame is volatile, although cut off the power hind saved data also won't be lost.

At that time, the memory chip prototype of all and other researcher uses polycrystal to provide a design, the design is complex, cost is high. To solve this one problem, partial researcher begins to check ambipolar transistor. But the heart that mount offer values metallic oxide semiconductor field effect transistor (the following abbreviation " MOSFET dog stairs for car " ) , he admits, "MOSFET i dog stairs and ramps s reall dvd discovery 4 y insufficient and advanced, and put in a few problems, but I still think it has an outlook very much. But I still think it has an outlook very much..

The heart that mount offer makes the location that gave to use monocrystal to provide a design eventually, filed patent 1968, but the world that stores chip market remains polycrystal to be in charge of DRAM chip, till acting 1970 metaphase, firs most popular selling dog crates large t DRAM chip that uses monocrystal to provide a design just c most popular selling dvd discovery omes out.
