MRAM - the key to a new era of computers images 1 Scientists at Johns Hopkins University (USA) have successfully developed random access magnetic memory (MRAM) of computers. This technology could usher in a new era of high-speed computing, large information capacity and low energy consumption.

US scientists have discovered unusually shaped nano or cobalt nano rings that can be used as memory cells. These rings are extremely small in size, about 100 nanometers (1 nanometer is 1 billionth of a meter) but have enormous information capacity. The asymmetrical structure of nickel or cobalt nano rings makes it unaffected by other magnetic fields that may appear in the computer when working. The process of creating these asymmetric nano rings is a new technology secret.

US scientists believe that computers with MRAM sets made up of cells consisting of nickel or cobalt nanoparticles will be extremely high, small in size with hard drives, but can be stored up to 100 movies. The power consumption of this computer is 99% less than the current computer, especially without losing the data on the computer when the power supply is unexpectedly lost.
