Scientists at Johns Hopkins University in the United States have successfully developed a new type of magnetic random-access memory (MRAM) for computers. This technology could usher in a new era of high-speed computing with large data storage capacity and significantly lower energy consumption.
American scientists have discovered that unusually shaped nano-rings made of nickel or cobalt can be used as memory cells. These rings are extremely small, with a diameter of about 100 nanometers (1 nanometer equals one billionth of a meter), yet they have an enormous information storage capacity. The asymmetrical structure of the nickel or cobalt nano-rings allows them to be unaffected by other magnetic fields that may arise in computers during operation. The process of creating these asymmetrical nano-rings is a new technological secret.
The researchers believe that computers equipped with MRAM made from cells consisting of nickel or cobalt nano-rings will achieve incredibly high speeds and small sizes, with hard drives no larger than a coin but capable of storing over 100 movies. Additionally, the energy consumption of these computers could be reduced by up to 99% compared to current machines, and they would notably not lose data when power is unexpectedly lost.
