BM is developing a new type of ultra-low-cost

Solid-state memory featuring a storage capacity that vastly exceeds what today’s hard disk drives can provide. Called racetrack memory, the technology may one day replace hard disk drives in PCs, laptops and servers as well as displace flash memory chips in smartphones, digital cameras, and tablets.
The radically new type of storage memory is
Based on a breakthrough technology known as spintronics, which manipulates the two types of independent electrons found in electrical current — called the “spin-up” and telegram number list “spin-down” electrons. The goal is to enable computing devices to store bits of information by manipulating the magnetic state of a region within a nanowire that is just a few tens of nanometers wide.
“We discovered that domain walls don’t hit
Peak acceleration as soon as the current is turned on — it takes them exactly the same time and distance to hit peak acceleration as it does to decelerate and eventually come to a stop,” said IBM Research Fellow Dr. Stuart Parkin on Thursday. “Now we know domain walls can be positioned precisely along the racetrack simply by varying the length of the current pulses, even though the walls have mass.”
