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

Bit net (ChinaByte)6 month 20 days of messages, according to 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 he dog crates large dogs art 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 dvd discovery 3 Theory) . Scale theory was elaborated how to narrow ceaselessly transistor dimension, development is smaller, faster, cheaper the method of chip. The heart that mount offer says scale theory is mixed rub E dog crates large strong r 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 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, and the price costly, rate is slow, but fi dog cra dog stairs and ramps tes large breed dog crates large rstly 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 " ) , he admits, "MOSFET is really insufficient and advanced, and put in a few pro dvd discovery best buy blems, 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 dog stairs for bed the world that stores chip market remains polycrystal to be in charge of DRAM chip, till acting 1970 metaphase, first DRAM chi dvd discovery p that uses monocrystal to provide a design just comes out.
