Will 'Genetic Hard Drives' Revolutionize The Way Computers Work?

Currently data centres such as Google's shown here, rely on traditional hard drives. However, they could one day be replaced by the DNA drives revealed today 

The 'Genetic Hard Drive' That Could Store The Complete Works Of Shakespeare (And Revolutionize The Way Computers Work) -- Daily Mail 

* Same technique also used to store 26 second excerpt from Martin Luther King's 'I Have A Dream' speech
* Breakthrough could have major implications for computer storage with DNA hard drives
* Could lead to drives that can store high definition version of every film and TV programme ever created in a teacup sized drive

A genetic storage device has been used to 'download' all 154 of Shakespeare's sonnets on to strands of synthetic DNA.

Scientists were then able to decode the information and reproduce the words of the Bard with complete accuracy.

The same technique made it possible to store a 26 second excerpt from Martin Luther King's 'I Have A Dream' speech and a photo of the Cambridgeshire laboratory where the work took place.

Researchers were also able to turn a copy of Watson and Crick's paper describing the nature of DNA into genetic code.

Memristors: A Different Kind Of Computer Memory Chip

Memristors employing more "exotic" materials will probably make it into devices first

Memristors In Silicon Promising For Dense, Fast Memory -- BBC

Researchers have revealed details of a promising way to make a fundamentally different kind of computer memory chip.

The device is a "memristor", a long-hypothesised but only recently demonstrated electronic component.

A memristor's electronic properties make it suitable for both for computing and for far faster, denser memory.

Researchers at the European Materials Research Society meeting now say it can be made much more cheaply, using current semiconductor techniques.

Transparent Memory Chips – The Next Step in Memory Storage -- Sci-Tech Daily

As technology moves forward, things get smaller, faster and now possibly transparent. A team of scientists have developed transparent, flexible memory chips that may one day replace flash drives and other personal data storage devices.

New memory chips that are transparent, flexible enough to be folded like a sheet of paper, shrug off 1,000-degree Fahrenheit temperatures — twice as hot as the max in a kitchen oven — and survive other hostile conditions could usher in the development of next-generation flash-competitive memory for tomorrow’s keychain drives, cell phones and computers, a scientist reported today.

Magical BEANs: New Nano-Sized Particles Could Provide Mega-Sized Data Storage

From Science Daily:

ScienceDaily (Sep. 20, 2010) — The ability of phase-change materials to readily and swiftly transition between different phases has made them valuable as a low-power source of non-volatile or "flash" memory and data storage. Now an entire new class of phase-change materials has been discovered by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley that could be applied to phase change random access memory (PCM) technologies and possibly optical data storage as well. The new phase-change materials -- nanocrystal alloys of a metal and semiconductor -- are called "BEANs," for binary eutectic-alloy nanostructures.

Hewlett Packard Outlines Computer Memory Of The Future

Image: 17 memristors captured by an atomic force microscope

From The BBC:

The fundamental building blocks of all computing devices could be about to undergo a dramatic change that would allow faster, more efficient machines.

Researchers at computer firm Hewlett Packard (HP) have shown off working devices built using memristors - often described as electronics' missing link.

These tiny devices were proposed 40 years ago but only fabricated in 2008.

HP says it has now shown that they can be used to crunch data, meaning they could be used to build advanced chips.

That means they could begin to replace transistors - the tiny switches used to build today's chips.
