RAM that uses magnetic materials to improve energy usage and efficiency developed

Researchers have developed a new RAM that makes use of magnetic materials to improve energy usage and efficiency. This kind of RAM is said to enhance bit reading and also, the writing speed of PC.

RAM is the short form of Random access memory, it's one of the physical parts located inside the computer system that can temporarily store data, it is sometimes called the "working memory" of a computer. Generally, RAM enhance the speed of a computer.

RAM is not only meant for computers, it is useful in mobile phones, tablets, and in other kinds of gadgets which require memory capabilities. In other devices like mobile phones, tablets, it is known as system memory. Information can be easily stored and retrieved from Random access memory.

To refresh and maintain the information stored in the RAM, there should be constantly applied voltage.


Researchers involved in the research from the Moscow Institute of Physics and Technology (MIPT) acknowledged that power is necessarily required to store and access data from the RAM but they suggested that , a new magnetic design for RAM sticks may be able to drastically reduce the power a normal RAM requires.

MIPT scientists, together with some Scientists from the Kotelnikov Institute of Radio Engineering and Electronics (IRE) of the Russian Academy of Sciences (RAS) and the International Associated Laboratory of the Critical and Supercritical Phenomena in Functional Electronics, Acoustics, and Fluidics, have been able to create magnetic RAM prototypes resulting in a "substantial energy saving."

According to the principal researcher Sergei Nikitov, deputy head of MIPT's Section of Solid State Physics, Radiophysics and Applied Information Technologies,
so far, the RAM technology has been rapidly advancing, with memory modules becoming ever faster. However, this type of memory has one major limitation that cannot be overcome, namely its low energy efficiency. In this paper, we present the magnetoelectric memory cell. It will reduce bit-reading and -writing energy consumption by a factor of 10,000 or more.


The Team equally added that magnetization takes a particular orientation and storing of information which directly depend on the nature of the strain. They also said that
the changing orientation of the magnetic field gives rise to increased voltage in the sample. By detecting this voltage, the state of the memory cell can be determined. But the reading operation might affect magnetization; therefore, it is necessary to recommit the value that has been read to the memory cell.

The team developed a prototype using the new, magnetized structure, and discovered that with a test piece of roughly one millimeter across, the memory cells worked well and with a far lower energy consumption.

MIPT says that the design could be scaled down further without any impact on efficiency or power usage, which makes magnetoelectric RAM (MELRAM) "promising" for computer hardware which demands low energy consumption but high read/write rates. In addition, the structures could act as a blueprint for nano-sized memory cells.
