READING METHOD OF MAGNETORESISTIVE DEVICE

摘要

PURPOSE: A reading method of a magnetoresistive device is provided to set the magnetization of a reference layer to a predetermined orientation transiently and checking the resistance state of the magnetoresistive device. CONSTITUTION: A magnetoresistive device includes a data layer and a reference layer. The magnetization of the reference layer is transiently set to a predetermined orientation(110). The resistance state of the magnetoresistive device is checked(112). Preferably, the resistance state of the device is decided by applying a predetermined voltage across the device and detecting the current flowing through the device. Preferably, the resistance state of the device is decided by applying a bipolar pulse to the device and detecting the resistance transition of the device.
