Bias-adjusted magnetoresistive devices for magnetic random access memory (MRAM) applications

摘要

A method and apparatus are presented for shifting a hysteresis loop of a magnetoresistive device. For example, a method provides for applying a bias current to a word line of the magnetoresistive device during either a read sequence or a write sequence. The bias current is preferably configured to substantially center a hysteresis loop of the device without switching a binary state of the device.
