Quick Introduction
1. In this world there is a time to time improvement in the electronics field
.One such improvement in this field is"RACE TRACK NANOMAGNETIC MEMORY“ replacing the present day solid state “HARD DISK DRIVES” and “FLASHMEMORIES”.
2. This can bring a new revolution with its extraordinary features like:Great improvement in storage capacity of the system when compare to the normal HDD and FLASH memories . Decrease in the cost per GB of memory This new class of memory named "racetrack" is internally built with a u-shaped nano
magnetic wire through which a polarized electric current is made to slide or “race" through tiny magnetic patterns around the nanowire "track," where the device can read and write data in less than a nanosecond Before going to know about how this memory works let’s know about
SPINTRONICSSpintronics(Putting electronics in a spin)
the storage of bits generated by the magnetic spin of electrons rather than their charge
POLARISED CURRENT:
It is the current with charge particles spinning only one sense which in-turn produce Magnetic field Construction:
It consists of a Nano magnetic material which is in U-shape. It consists of two tracks. First track: Polarized current passes through it Second track: For storing the domain wall pattern
Applications:
- 1. Significant role in high density data storage,microelectronics, and Bio-medical applications etc.
2. This project will bring together expertises in several different disciplines and will carry out collaborative research area .
3.Particularly attractive for memory storage. An mp3 player can store 3500 movies and 500000 songs.
4.Applications in magnetic sensors.
5.Potenially used in quantum computing where electron spin would represent a bit (called qubit ) of information.
Advantages:-
The promise of racetrack memory - for example, the ability to carry massive amounts of information in your pocket - could unleash creativity leading to devices and applications that nobody has imagined yet."Due to this extraordinary features it replaces the present flash and hard disk memory Its cheaper compared to other memory devices existing today . As there are no moving parts the power consumption is less when compared to other devices which comprises of movable parts. The life time of device is considerably very long when compared to other devicesMassless motion

plz send me.... more information about this topic

is there any word document for this race track nanomagnetic memory
