Protein a good source for chips

Japanese ferritin about

HOORAY for the Japanese, they’ve solved the age old chip/protein conundrum.

Matsushita said it has developed a chip-making technology which uses protein to make high-performance memory chips.

The development was the work of boffins at Matsushita, Tohoku University, the Tokyo Institute of Technology and Osaka University. And others – well, you know what it’s like when you have chips. People materialize from all over the place.

Their research results will be announced today at the Japanese Society of Applied Physics in Funabashi, Chiba Prefecture. So get your coat on and get over there.

You too can make memory out of protein. Here’s how.

Take some ferritin - you know, the hollow, spherical-shaped protein with a diameter of about 12 nanometers. Mix ferritin with a liquid solution of metals, and allow metal particles to seep into the ferritin’s cavities.

Give it a bit of time. Maybe you could tidy up the kitchen in the meantime.

Next, you filter the solution to remove alkali metals, as they cause
malfunctions in semiconductor chips. Then drip liquid onto a silicon substrate (available from the usual sources). You’ll find the Ferritin lines up on the substrate in an orderly fashion – in the trade we call this self-organization – along a pattern created using an organic membrane.

Now you’ll want to wash and dry the silicon substrate with the liquid. Then pop it in an oven and heat up to 500 C. This removes the protein and leaves just metal particles on the substrate. Feed some electricity in and the resulting substrate should display the electrical characteristics necessary for a memory element.

By using ultrafine processing at several nanometer levels, the technology could make it possible to develop a stamp-size memory chip with a 1-terabyte data capacity, according to Nikkei.

The developers hope to create a commercially-available technology in five ye ars. So in five years we may get cheap memory chips that have 30 times the data capacity of today’s cutting edge technology.

Horse Chips!

This grubs at the very roots of chips.
Not withstanding the 1tb achievement
(1tb? I must be off my mount! Please allow me to vent my steed's spleen, ready for the glue binning tho I may be), various company's livery of ferritin burling is a well pedigreed carriage for magnetic media. Not to hit anyone over the withers with a carrot and a stick; the use of protein should be taken with a grain of salt, if one is over-egging this food for thought thusly as "Protein" *must needs* be[ing] a new ingredient to a souped-up concoction. You would not be leading down the garden path? That would chomp the biscuit, cud. Great Heady Night Mares!

Suitable cages are, for instance, cryptates, calixarenes, hemispherands, buckyballs, buckytubes, and proteins with a spherical tertiary structure.

Proteins are particularly suitable because their cavity can be large enough to be used as growing site for the crystalline particles. An extremely suitable protein is ferritin, apoferritin, or derivatives thereof. Ferritin occurs in the spleen and liver of higher animals, for instance in horse spleen, and is commercially available.

The term "crystal seeds" means ions, atoms, molecules, or aggregates thereof, which can nucleate and grow to a crystalline particle.

The use of ferritin and apoferritin for the synthesis of inorganic nanophase materials has been disclosed in US patent 5,358,722, and by Meldrum et al.

in Nature, Vol. 349, pp. 684-687 (1991). The synthesis of magnetic minerals by using these proteins has been disclosed by Meldrum et al. in Science, Vol. 257, pp. 522-523 (1992).

11. A data storage device comprising a support or a substrate with on it the crystalline particles as obtained by the method according to any one of claims 1-9.

Approved for use in storage electronic devices.

CHEAP is Smiley Face.

Looks like Someone named lsb did research?, Mainly I feel word is 30X & Cheap. Obviously 1,2,-4,8, & 16 gb memory prices are boing to converge to 1 gb level or ~$100. Someday Terrabyte memory will be about same cost.Not sure what (desktop/workstation) to use it in, however.Maybe ?True 64 bit NT7. Anyone rasie me an NT8?

Say again.

Stamp sized? Since stamps only seem to get bigger and chips smaller stamp size is not good nor competitive.
