ABSTRACT:
A new magnetic spin transistor is provided. This spin transistor can be used as a memory element or logic gate, such as an OR, AND, NOT, NOR and NAND gate. The state of the magnetic spin transistor logic gate is set inductively. This new magnetic spin transistor/gate can be operated with current gain. Furthermore, inductive coupling permits the linking of multiple spin transistors and spin transistor gates to perform combinational tasks. A half adder embodiment is specifically described, and other logic gates and combinations of half adders can be constructed to perform arithmetic functions as part of a microprocessor.
