Abstract
A self-reference storage structure includes: three transistors, including a first transistor T, a second transistor T, and a third transistor T; and two magnetic tunnel junctions, including a first magnetic tunnel junction MTJand a second magnetic tunnel junction MTJ. The first magnetic tunnel junction MTJis connected in series between the first transistor Tand the second transistor T, and the second magnetic tunnel junction MTJis connected in series between the second transistor Tand the third transistor T. When the first transistor T, the second transistor Tand the third transistor Tare turned on, one-bit binary information is written; and when data is stored, one-bit binary write can be implemented only by applying an unidirectional current pulse.
