NCSU's Fingernail-Size Chip Can Hold 1TB 227
CWmike writes "Engineers from North Carolina State University have created a new fingernail-size chip that can hold 1 trillion bytes (a terabyte) of data. They said their nanostructured Ni-MgO system can store up to 20 high-definition DVDs or 250 million pages of text, 'far exceeding the storage capacities of today's computer memory systems.' Using the process of selective doping, in which an impurity is added to a material whose properties consequently change, the engineers worked at nanoscale and added metal nickel to magnesium oxide, a ceramic. The resulting material contained clusters of nickel atoms no bigger than 10 square nanometers — a pinhead has a diameter of 1 million nanometers. The discovery represents a 90% size reduction compared with today's techniques, and an advancement that could boost computer storage capacity. 'Instead of making a chip that stores 20 gigabytes, you have one that can handle one terabyte, or 50 times more data,' said the team's leader, Jagdish 'Jay' Narayan, director of the National Science Foundation Center for Advanced Materials and Smart Structures at the university."

Re:There is no chip. (Score:5, Interesting)
These days the quality of memory is crap though. Just look at NAND flash: there are hundreds of failed blocks on most chips, and these days sectors with a bad bit or two are used and just error corrected. Same with hard disks. You work around this by shoving large amounts of error detection, correction, and relocation logic into the controller.
Let's say each individual bit (!) can be manufactured reliably 99.99% of the time. For a 2048-byte sector (typical for NAND flash), using sector-granularity remapping, there's a ~20% chance of a sector being good. That's not very good, but it still gives you 19% usable capacity. At a terabyte per chip, that's still 190GB of storage. If you add single-bit error correction, you'd get 500GB of storage. At 2-bit correction, 750GB. Current generation Flash memory already uses multiple-bit ECC for MLC level flash memory (where typically 2 bits will fail at once), and sectors with one bad bit(pair) are considered "good enough" and corrected away. If you can manufacture this 1TB storage chip at 99.99% per bit, and especially if most of the failures will happen at manufacture time and not develop later during use, I'll gladly take it given a reasonable amount of error correction wrapping it. It's not like we don't already rely on ECC for our day-to-day storage.
Yield issues affect mainly things like CPUs with no redundancy. With memory, you just lose the damaged parts. Even RAM these days is manufactured with spare blocks that can replace blocks that came out wrong, to increase yield (though it's usually only a few and the remapping is burned in at the factory).

We have investigated the magnetic properties of the Ni-MgO system with an Ni concentration of 0.5 at.%. In as-grown crystals, Ni ions occupy substitutional Mg sites. Under these conditions the Ni-MgO system behaves as a perfect paramagnet. By using a controlled annealing treatment in a reducing atmosphere, we were able to induce clustering and form pure Ni precipitates in the nanometer size range. The size distribution of precipitates or nanodots is varied by changing annealing time and temperature. Magnetic properties of specimens ranging from perfect paramagnetic to ferromagnetic characteristics have been studied systematically to establish structure-property correlations. The spontaneous magnetization data for the samples, where Ni was precipitated randomly in MgO host, fits well to Bloch's T3/2-law and has been explained within the framework of spin wave theory predictions.

Anyone who knows anything at all about quantum mechanics knows that the spin of an electron is quantized and cannot change.
The Wikipedia article has this to say about spintronics:
Electrons are spin-1/2 fermions and therefore constitute a two-state system with spin "up" and spin "down". To make a spintronic device, the primary requirements are to have a system that can generate a current of spin polarized electrons comprising more of one spin species—up or down—than the other (called a spin injector), and a separate system that is sensitive to the spin polarization of the electrons (spin detector). Manipulation of the electron spin during transport between injector and detector (especially in semiconductors) via spin precession can be accomplished using real external magnetic fields or effective fields caused by spin-orbit interaction.
This makes MUCH more sense! Reporters are always notorious for getting the science wrong.
