    Abstract: A resistance based memory sensing circuit (302) has reference current transistors (310, 312) feeding a reference node (204) and a read current transistor (308) feeding a sense node, each transistor has a substrate body at a regular substrate voltage during a stand-by mode and biased during a sensing mode at a body bias voltage lower than the regular substrate voltage. In one option the body bias voltage is determined by a reference voltage on the reference node. The substrate body at the regular substrate voltage causes the transistors to have a regular threshold voltage, and the substrate body at the body bias voltage causes the transistors to have a sense mode threshold voltage, lower than the regular threshold voltage.

    Abstract: In a Spin Transfer Torque Magnetoresi stive Random Access Memory (STT-MRAM) a bit cell array can have a source line substantially parallel to a word line. The source line can be substantially perpendicular to bit lines. A source line control unit includes a common source line driver and a source line selector configured to select individual ones of the source lines. The source line driver and source line selector can be coupled in multiplexed relation. A bit line control unit includes a common bit line driver and a bit line selector in multiplexed relation. The bit line control unit includes a positive channel metal oxide semiconductor (PMOS) element coupled between the common source line driver and bit line select lines and bit lines. Write disturb is prevented by setting a voltage associated with unselected ones of the bit lines equal to a selected source line.
