Now entire library on chip developed by Indian-American
Washington: An Indian-American scientist has developed a computer chip that can store an unprecedented amount of data - enough to hold an entire library.

The new chip stems from a breakthrough in the use of nanodots, or nanoscale magnets, and represents a significant advance in computer-memory technology.

"We have created magnetic nanodots that store one bit of information on each nanodot, allowing us to store over one billion pages of information in a chip that is one square inch," says Jay Narayan, professor of Materials Science and Engineering at North Carolina State University (NCSU).

Narayan, a product of the Indian Institute of Technology (IIT), Kanpur, conducted the study. The breakthrough is that these nanodots are made of single, defect-free crystals, creating magnetic sensors that are integrated directly into a silicon electronic chip.

These nanodots, which can be made uniformly as small as six nanometres in diameter, are all precisely oriented in the same way - allowing programmers to reliably read and write data to the chips, an NCSU release said. A nanometre is the billionth of a metre.

The chips themselves can be manufactured cost-effectively but the next step is to develop magnetic packaging that will enable users to take advantage of the chips - using something, such as laser technology, that can effectively interact with the nanodots.

The research was presented at the Materials Research Society Spring Meeting in San Francisco.

2: "It Appears as if were another Internet Hoax"

The names & description of the chips don't have those charming technical terms. The content lacks lucid representation of facts

The chip can hold at max 10^14 bits of data.Now you calculate...This article seems to be lucid as the technology is still under construction (as it states) and yet to be main streamed to be built as a technology.

4: This article has only vague description about Chip itself. In Storage technology, amount of storage is measured in bits and bytes. It would be better if articles like this includes specifications. "Entire Library" is relative term.

5: I think what is being done here is to highlight the fact that he is an Indian, which I understand and can respect. We need to beat our own chest, I guess. While doing that the more important thing is to provide substance, separate fluff from hard data. May be Silicon India can put together information that has more meat. Links that are connected to papers that has more detail. A little more in-depth than thin layer description. This will help to separate marketing glitz and "we Indians are so intelligent and great" to "here is the deep technical level description" and then let people conclude that you are great. Any commentary that talks about what the level of maturity this would help. Is this research? Is this a product? Key advantages and disadvantages compare and contrast would help. Just billions of pages of storage is worthless, if you can build 100/year, or the chip dies after 10,000 accesses, or it takes $1000 to build the chip or the MTBF is 2000 hours, and so on. There are so many aspect here that Silicon India can report on to give the reader a better understanding. I would appreciate a response from Silicon India.

Hi Bhide
it is not a chest beating ,this news will encourage Indian kids ,Indians in India it is a country with 1 biilion plus people still 300-400 million below poverty what it will do is encourage Indians towards pure science study ,Dr Apj Abdul Kalam who was our ex president and eminent scientist is also on a similar mission to spur young Indian minds at school to dream and go achieving about them this has a magical effect yes some will go abroad ,some will pursue other stuff due to circumstances ,but even one young mind from each school becomes a next Dr Apj Abdul Kalam and joinsd ISRO ,Agricultural Research Intsitute or even IAS and makes contribution for India ,it will have a profound effect for upliftment of Indians ,that is the essence.
Silicon india is not science journal ,generally any break throughs are first published in science journals with in depth abstract.graphs and conclusion if silicon india reproduces that content then it will be a science journal.It is doing the right thing reporting it ,if you need to verify or a fellow academician you can access their finds by just going to google.
Watch out mate our attitude is a bit out of sync with majority of readers here ,most people here would like positive news and new findings like this are all the more encouraged .

Now it will go to the Validation Process. Keep a positive approach about Indians.

Hi Ateeq
thank you ,I whole heartedly agree with you ,the science jouranal that contains the paper published will list background,abstratct ,in depth comparisions,benefits,conclusion by the authors ,Bide is a bit stretching it has an issue here,silicon India will not reproduce that content ,can only report it as a news.Silicon India is not a science journal.

We are taking here about 11TB of data in a 1 sq. cm of a chip :).This is what my calculation says.

If it is a research paper it will be publsihed and verified by fellow academics ,it will contain data about new methods of storage to other storage prior to this find ,it will highlight all advantages ,cost benefits and a conclusion section in the end.
Silicon India did the right thing to report it better than a movie gossip,Unnecessary India bashing (like times of india sometimes does),other negative news.
It is much better if you do not like do not access this site go elsewhere .
This site has millions of hits in USA alone

yes mr Raj
Unsubsribe by all means thank you very much .Iam reading this site for last six years ,it is different to rediff ,rediff reports some tabloid news like which bollwood diva sizzles ,silicon india never does such news so it is not comparable to rediff ,it got mentoring by fellow IT professionals,it is a magazine that focuses on more in depth articles which you need to subscribe (probably pay a subscrition) what we are just accessing is the free stuff ,that is why it is short and condensed .

It is just a research paper, nothing is materialized. I think I need to unsubscribe from this site's newsletter, because the quality of the articles posted here is like rediff. Just fancy titled craps
