发明名称 RECORDING METHOD FOR MAGNETIC MEMORY DEVICE
摘要 [Object] To provide a recording method for a magnetic memory device including a recording layer that is capable of changing a magnetization direction and holds information as a magnetization direction of a magnetic body and a magnetization reference layer that is provided with respect to the recording layer with an insulation layer interposed therebetween and becomes a reference of the magnetization direction, the magnetic memory device being recorded with information by a current flowing between the recording layer and the magnetization reference layer via the insulation layer, the recording method being capable of maintaining, even when a write pulse considerably higher than an inversion threshold value is applied, a write error rate of 10−25 or less that is obtained when a write pulse a little larger than the inversion threshold value is applied. [Solving Means] While taking time of 2 ns or more, write power injected at a time a write pulse falls is reduced gradually. At this time, it is favorable to keep a rate of decline of a voltage of the write pulse at the time of the fall small until the voltage of the write pulse at the time of the fall becomes smaller than an inversion threshold voltage of the magnetic memory device.
