Current bending yields low-power magnetic memory

by Harry Baggen @ elektormagazine.com:

Magnetic random-access memory (MRAM) is faster, more efficient and more robust than other data storage media. MRAM stores data by making clever use of electron spin – a sort of gyroscopic property of electrons. Because it used magnetism instead of stored charge, MRAM is nonvolatile, which means that the stored data can survive a power outage. MRAM also uses much less current. However, high peak currents are necessary to flip the electron spins in the right direction to store the data.
