IBM, realizing "racetrack" recording technology with a recording capacity of 100 times and ultra-low power consumption and low cost

It seems that IBM has taken a step to realize a memory that combines high performance and reliability which is the characteristic of flash memory, low cost and high capacity which are characteristics of HDD.

If you realize it, low-cost memory capacity will be about 100 times higher than in the past, yet a dreamlike memory of ultra low power consumption will emerge.

Details are as below.

According to this release, IBM announced research papers on the principle and outcome of memory technology called "racetrack (race track)".

This is to record on a magnetic material vertically or horizontally arranged on the surface of silicon wafer by applying HDD capable of storing data at a cost equivalent to one hundredth of that of flash memory, which is a problem of HDD And the reduction in reliability due to mechanical wear was cleared by using what is called "electron spin" without using moving parts.

This is the diagram explaining its principle. By IBMCommentary on moviesIt is also done.


In addition, by storing data using "magnetic tunnel junction device (MTJ)" in a portion called "domain wall" that has been considered difficult since 50 years ago, the recording capacity of 10 to 100 times It can be realized.

If further research will be carried out, it is said that the power consumption for manipulating domain walls which is a problem can be reduced, and eventually it will operate for several weeks with one battery and use for decades It is said that large capacity personal storage that can be realized may be realized.
