    摘要: Systems and methods to reduce source loading effects in STT-MRAM are disclosed. In a particular embodiment, a method includes determining a switching current ratio of a magnetic tunnel junction (MTJ) structure that enables stable operation of a memory cell. The memory cell includes the MTJ structure serially coupled to an access transistor. The method also includes modifying an offset magnetic field that is incident to a free layer of the MTJ structure. The modified offset magnetic field causes the MTJ structure to exhibit the switching current ratio.

    摘要: A Spin Transfer Torque Magnetoresistive Random Access Memory (STT-MRAM) and associated read operations are disclosed. A bit cell includes a magnetic tunnel junction (MTJ) and a word line transistor, the bit cell being coupled to a bit line and a source line. A clamping circuit is coupled to the bit line and is configured to clamp the bit line voltage to a desired voltage level during a read operation of the STT-MRAM to prevent the bit line voltage from exceeding the desired voltage level. The desired voltage level is less than a write voltage threshold associated with a write operation of the STT-MRAM.
