A researcher at the University of the State of North Carolina has developed a memory chip using nanodots small sizes. The fact that the number of articles on the topic of nanodots multiplies is a very good sign. To recall, last week, we brought back the results of French researchers who developed a rewritable memory nanodots. The U.S. research on memory seems to like using different materials.

If we are still far from commercialization than the most optimistic do not envisage at least five years, the popularity of the scientic community that continues to advance toward the creation of chips can be manufactured on a large scale in existing plants is very promising.

In this case, American research showed for the first time ever, it was possible to create a nanodot of only 6 nm in diameter composed of crystals without defects and combined with magnetic sensors placed directly on the layer silicon. Concretely, this would create a memory chip with a density of almost 4 TB per square inch. The problem is that scientists have yet to packaging to communicate with the chip. Remember, the nanodots are very small magnets whose polarity (p = 1 or p =- 1) can represent binary data (1 or 0).
