Switching Current Fluctuation And Repeatability for MRAM with Propeller Shape MTJ

In this paper, a write error rate, when the function test on this magnetic tunnel junctions (MTJ) is continued repeatedly, is estimated from the write margin and switching current fluctuation. This paper also reveals how the write sequence influences these results.The switching current fluctuation is strongly dependent on the turn-on sequence, which is related to the magnetization reversal mode.
