Magnetic random access memory array with free layer locking mechanism and method of its use
摘要:
A method of using an MTJ MRAM cell element having two magnetization states of greater and lesser stability. During switching, the free layer is first placed in the less stable state by a word line current, so that a small bit line current can switch its magnetization direction. After switching, the state reverts to its more stable form as a result of magnetostatic interaction with a SAL (soft adjacent layer), which is a layer of soft magnetic material formed on an adjacent current carrying line, which prevents it from being accidentally rewritten when it is not actually selected and also provides stability against thermal agitation.
