Racetrack memory is an experimental non-volatile memory device under development at IBM's Almaden Research Center. In early 2008, a 3-bit version was successfully demonstrated.Racetrack memory uses a spin-coherent electric current to move magnetic domains along a nanoscopic permalloy wire about 200 nm across and 100 nm thick. As current is passed through the wire, the domains pass by magnetic read/write heads positioned near the wire, which alter the domains to record patterns of bits. A racetrack memory device is made up of many such wires and ....etc

ABSTRACT
While magnetic and semi-conductor based information storage devices have been in use since the middle 1950â„¢s, todayâ„¢s computers and volumes of information require increasingly more efficient and faster methods of storing data. Among the most promising of the new alternatives are photopolymer-based devices, holographic optical memory storage devices, and protein-based optical memory storage using rhodopsin , photosynthetic reaction centers. This paper focuses mainly on protein-based optical memory storage using the photosen ....etc

You hit the power button on your television and it instantly comes to life. But do the same thing with your computer and you have to wait a few minutes while it goes through its boot-up sequence. Why can't we have a computer that turns on as instantly as a television or radio? IBM, in cooperation with Infenion, is promising to launch a new technology that will eliminate the boot-up process. Magnetic random access memory (MRAM) has the potential to store more data, access that data faster and use less power than current memory technologies.

In the era of the Internet, massive amounts of information and multimedia have become easily accessible in every corner of the world. The decreasing cost of storing data, and the increasing storage capacities of ever smaller devices, have been key enablers of this revolution. Current storage needs are being met because improvements in conventional technologies - such as magnetic hard-disk drives, optical disks and semiconductor memories - have been able to keep pace with the demand for greater and faster storage.

However, there is strong e ....etc

Random access memory (RAM) is the best known form of computer memory. RAM is considered random access because you can access any memory cell directly if you know the row and column that intersect at that cell.
