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.

Hewlett Packard Outlines Computer Memory Of The Future

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.

Five Ways To Revolutionise Computer Memory

From New Scientist:

Once upon a time, not so long ago, the idea that you might store your entire music collection on a single hand-held device would have been greeted with disbelief. Ditto backing up all your essential computer files using a memory stick key ring, or storing thousands of high-resolution holiday snaps in one pocket-sized camera.

What a difference a decade makes. The impossible has become possible thanks to the lightning rise of a memory technology with the snazzy name of "flash".

Electronic Memory Chips That Can Bend And Twist

From Science Daily:

ScienceDaily (June 3, 2009) — Electronic memory chips may soon gain the ability to bend and twist as a result of work by engineers at the National Institute of Standards and Technology (NIST). As reported in the July 2009 issue of IEEE Electron Device Letters, the engineers have found a way to build a flexible memory component out of inexpensive, readily available materials.

Though not yet ready for the marketplace, the new device is promising not only because of its potential applications in medicine and other fields, but because it also appears to possess the characteristics of a memristor, a fundamentally new component for electronic circuits that industry scientists developed in 2008. NIST has filed for a patent on the flexible memory device (application #12/341.059).

How A Future AI May Contain Information And Memories

A neuron receives and processes information through a network of branches called dendrites. Once it processes the signal, the brain cell relays it along an axon to a terminal linking to another cell's dendrites.

Single Brain Cell Can Hold a Memory -- Live Science

Memory has long been described as a function of brain cells getting together and forming connections. A new study finds single cells can remember things.

Individual nerve cells (called neurons) in the front part of the brain can hold traces of memories by themselves for up to a minute, perhaps longer.

The fleeting memories, which the researchers found in mice brains, are held in the most highly evolved part of the brain in a manner akin to the nonpermanent working memory of a computer.

"It's more like RAM [random access memory] on a computer than memory stored on a disk," said Don Cooper, assistant professor of psychiatry at the University of Texas Southwestern Medical Center. "The memory on the disk is more permanent and you can go back and access the same information repeatedly. RAM memory is rewritable temporary storage that allows multitasking."
