Data Integrity Preservation In Spin Transfer Torque Magnetoresistive Random Access Memory |
摘要 |
Systems, circuits and methods for controlling the word line voltage applied to word line transistors in Spin Transfer Torque Magnetoresistive Random Access Memory (STT-MRAM) are disclosed. One embodiment is directed to a STT-MRAM including a bit cell having a magnetic tunnel junction (MTJ) and a word line transistor. The bit cell is coupled to a bit line and a source line. A word line driver is coupled to a gate of the word line transistor. A write-back circuit configured to detect a read value of the bit cell and is configured to write back the read value to the bit cell after a read operation.
