ARLA/CLUSTER: A radiação TeraHertz poderia acelerar a memória de um computador 1000 vezes

[João Costa > CT1FBF]

Terahertz radiation could speed up computer memory by 1000 times

One area limiting speed in personal computing speed is memory --
specifically, how quickly individual memory cells can be switched, which is
currently done using an external magnetic field.

European and Russian scientists have proposed a new method using much more
rapid terahertz radiation, aka "T-rays," the same things used in airport
body scanners. According to their research, published in the journal
Nature, swapping out magnetic fields for T-rays could crank up the rate of
the cell-resetting process by a factor of 1000, which could be used to
create ultrafast memory.

The radiation is actually a series of short electromagnetic pulses pinging
the cells at terahertz frequencies (which have wavelengths of about 0.1
millimeter, lying between microwaves and infrared light, according to the
scientists' press release). Most of the recent T-ray experiments have dealt
with quick, precise inspections of organic and mechanical material. Aside
from quickly scanning you for contraband and awkward bulges at airports,
other proposals have involved using terahertz radiation to look into broken
microchip innards, peer into fragile texts and even comb airport luggage
for bombs.

But similar to those hypothetical applications, you won't see T-rays in
your PCs any time soon. The scientists have successfully demonstrated the
concept on a weak ferromagnet, thulium orthoferrite, and even found that
the terahertz radiation's effect was ten times greater than a traditional
external magnetic field, meaning the new method is both far faster and more
efficient. But the scientists have yet to publish tests on actual computer
memory cells, so it's unknown when, or if, T-rays will buzz around inside
your machine.
