摘要
Spin dependent tunnel junctions aimed for storage element in MRAM cells were switched between low and high resistance states using 20 ns current pulses on two perpendicular conductors. Switching was done in quasi static mode using an external field and dynamically with field pulses created on chip. For 20 ns pulsewidths the introduction of a delay between the two pulses promotes the switching at lower fields and reduces the dispersion in remanent resistance values after switching.
