Abstract:
A magnetic random access memory element is made from a first magnetic tunnel junction and a second magnetic tunnel junction. A latching circuit includes a false node that is connected to the first magnetic tunnel junction and a true node that is connected to the second magnetic tunnel junction. A pair of complementary bit lines are provided in association with the element. A first access transistor inter-connects a false one of the bit lines to the false node of the latching circuit, while a second access transistor inter-connects a true one of the bit lines to the true node of the latching circuit. The memory element accordingly has an SRAM four transistor (4T) two load (2R) architecture wherein the resistances associated with the two magnetic tunnel junctions provide the two load resistances.
