Researchers from Eindhoven's University of Technology (TU/e) managed to use a bending current to change an MRAM "bit". The result is a much more efficient memory write cycle that is also faster than conventional MRAM methods.

MRAM bit change by bending current

The idea is to use a current pulse under the MRAM cell bit which bends the electrons at the correct spin upwards towards MRAM bit. This was achieved before, but using a magnetic field. In this new method, the researchers applied an anti-ferromagnetic material to the top of the MRAM bits, which enabled the requisite magnetic field to be frozen.
