6-nanometer-sized magnetic nanometer dot successfully developed

According to reports, American scientists have made significant advances in the nanodot technology. They have developed a "super" computer chip that can accommodate the entire library's data. Researchers said that this is also a major aspect of computer storage technology. progress.
Gardner Narayan, a professor of magnetic materials technology and engineering at the University of North Carolina, leader of the study, said that the research team's breakthrough is that these magnetic nano-dots are made from flawless crystals. Researchers created magnetic sensors and integrated them directly onto a silicon electronic chip, resulting in magnetic nanodots. The scientists unified these nano-dots to a size of 6 nanometers, and then used the same method for precise positioning, enabling the program to read and write data stably.
Narayan believes that magnetic nano dots represent a revolutionary information storage technology. If each byte of 6 nanometer-sized dots stores one byte of information, then each chip can store more than 10 bits. (Terabit) data (1 terabyte can store 25 million pages of data), so that the chip library will become a reality. The cost of the chip itself is also very low, and researchers are going to develop magnetic packages that will allow users to make good use of the chip.
Previously, the research team successfully developed a 7-nanometer-size magnetic nano-nickel dot, and the memory conspiracy was increased 500 times to reach 10 trillion bits per square inch. At this density, the size of a coin-sized chip can reach 5 megabits, and the entire library of U.S. KK can be installed in a pocket.
In October of 2009, the research team announced that they obtained a ceramic-like material by adding metallic nickel atoms to magnesium oxide ceramic materials at the Nazi scale. The size of the nickel clusters in the new material is only 10 square nanometers, compared to the current semiconductor industry. The used storage unit is 90% smaller. In this way, the memory chip using this material can provide a capacity of 1TB or more under the size of the fingernail cover, equivalent to storing 20 HD movies or 2.5 million pages of documents, which is about 50 times the current memory capacity.
