IBM has for several years working to create ready to use industry-volatile memory of a new type. One of the most promising technologies is called Racetrack Memory. Such a system operates with a magnetic interaction, but not the electric current.
Principle recording Racetrack Memory is based on the movement of the so-called magnetic domains by spin currents. The developers were able to significantly reduce the size of the magnetic domains, which enabled and much higher than before, the recording density. All this was possible thanks to the development of technologies in the field of spintronic magnetic resistive devices and materials.
About a year ago, IBM laboratory in California have managed to create a working prototype of such a memory, its physical model. Specialists from the prototype memory module, able to create, move and detect magnetic beam, which in this system is the way to write a logic zero or one. Managed to generate not one but 250 magnetic domains in the described prototype system. Now IBM has completed work on the creation of reliable nanotubes of which are similar and the memory modules. This achievement brings the stage of practical implementation of the project, with the possibility of producing a new type of memory module.
In the future, they hope experts, namely Racetrack Memory will expand the capabilities of physical media, including container. With an equal amount of a standard carrier-based flash-memory, the new drive will be about 100 times larger volume. The number of write cycles theoretically infinite, in contrast to the same flash-memory.
Separate track memory module consists of a certain form of nanotubes, as well as two magnetic heads, producing reading and writing information. Magnetic domains in this case are means for transmitting information.
This picture "walks" on the web for over 6 years, but it reflects the optimal operation of the new memory i>
Normal portable media player, in the case of the practical implementation of research findings IBM, will receive a new type of medium volume up to 6-7 terabytes. According Stuart Parkin (an interesting interview with him can be found here ), now you can create a work module Racetrack Memory, and not just a prototype, and that trying to implement specialists from IBM. However, before the release of the technology in the light still needs to take a long time - about 4-5 years.
