#3d Computer Chips Could Be 1, 000 Times Faster Than Existing Ones A new method of designing and building computer chips could lead to blisteringly quick processing at least 1,
000 times faster than the best existing chips are capable of, researchers say. The new method,
which stores data, and the number-crunching processors in the same tiny space, said Max Shulaker, one of the designers of the chip,
and a doctoral candidate in electrical engineering at Stanford university in California. Reducing the distance between the two elements can dramatically reduce the time computers take to do their work
Shulaker said Sept. 10 here at the"Wait, What?""technology forum hosted by the Defense Advanced Research Projects Agency,
Progress slowing The inexorable advance in computing power over the past 50 years is largely thanks to the ability to make increasingly smaller silicon transistors,
the three-pronged electrical switches that do the logical operations for computers. According to Moore's law, a rough rule first articulated by semiconductor researcher Gordon E. Moore in 1965, the number of transistors on a given silicon chip would roughly double every two years.
Beyond that, shrinking transistors to the bitter end may not do much to make computers faster. Long commute time The main roadblock to faster computers is not flagging processor speed,
but a memory problem, Shulaker said. Big data analysis requires the computer to draw some tiny piece of data from some previously unknown spot in truly staggering troves of data.
Then the computer must shuttle that information via an electrical signal back and forth across the (relatively) vast inches of wire between the computer's memory (typically a hard drive)
and the processors, facing the speed bump of electrical resistance along the entire path.""If you try to run that in your computer,
you would spend over 96 percent of the time just being idle, doing absolutely nothing,"Shulaker said."
"You're wasting an enormous amount of power.""While the Central processing unit (CPU) waits for a piece of data to make the return trip from the memory, for instance,
the computer is still hogging power, even though it's not calculating a thing. Solving the memory-CPU"commute time,
"however, is tricky. The two components can't be put in the same wafer because silicon-based wafers must be heated to about 1, 800 degrees Fahrenheit (1, 000 degrees Celsius),
while many of the metal elements in hard drives (or solid state drives) melt at those temperatures, Shulaker said.
Carbon nanotubes To get around this issue Shulaker and his advisers at Stanford university, Subhasish Mitra and H.-S. Philip Wong, looked to a completely different material:
That computer, however, was slow and bulky, with relatively few transistors. Now, they have created a system for stacking memory and transistor layers,
and the resulting architecture can produce lightning-fast computing speeds up to 1, 000 times faster than would

In classical computers data is rendered as binary bits, which are always in one of two states:
0 or 1. However, a quantum bit (or ubit can exist in both of these states at once, a condition known as a superposition.

Rice university scientists make tantalum oxide practical for high-density devices Scientists at Rice university have created a solid-state memory technology that allows for high-density storage with a minimum incidence of computer errors.
The discovery by the Rice lab of chemist James Tour could allow for crossbar array memories that store up to 162 gigabits
Eight bits equal one byte; a 162-gigabit unit would store about 20 gigabytes of information.
Details appear online in the American Chemical Society journal Nano Letters. Like the Tour lab's previous discovery of silicon oxide memories, the new devices require only two electrodes per circuit,
"But this is a new way to make ultradense, nonvolatile computer memory, "Tour said. Nonvolatile memories hold their data even
when the power is off, unlike volatile random-access computer memories that lose their contents
when the machine is shut down. Modern memory chips have many requirements: They have to read and write data at high speed
and hold as much as possible. They must also be durable and show good retention of that data
while using minimal power. Tour said Rice's new design, which requires 100 times less energy than present devices,
has the potential to hit all the marks.""This tantalum memory is based on two-terminal systems,
This will be a real competitor for the growing memory demands in high-definition video storage and server arrays."
