IBM demonstrated 11nm STT-MRAM junction, says "time for STT-MRAM is now"
IBM researchers, in collaboration with Samsung researchers, demonstrated switching MRAM cells for devices with diameters ranging from 50 down to 11 nanometers in only 10 nanoseconds, using only 7.5 microamperes. The researchers say that this is a significant achievement on the way to high-density low-power STT-MRAM.
Using perpendicular magnetic anisotropy (PMA), the researchers can deliver good STT-MRAM performance down to 7Ã10-10 write-error-rate with 10 nanosecond pulses using switching currents of only 7.5 microampere.
