In this paper we have presented a novel design concept in hybrid CMOS-Nanomagnetic logic architecture and have shown it for a 2-input XOR. This paradigm is based on Shannon's expansion theorem and distributes the role of logic computation between the spin transfer torque magnetic tunnel junctions (STT-MTJs) and the CMOS metal lines. A 81.25% reduction in cell count and more than 75% reduction in energy...
Nanomagnetic Logic (NML) uses ferromagnetic and anti-ferromagnetic coupling to propagate information and to compute logic. In this paper we have addressed a layout constraint problem that surfaces in NML due to magnetic coupling based logic computation. The layout constraint problem poses a severe challenge to designing high density low power cascaded logic. After defining the problem and explaining...
Dipolar magnetic coupling between single layer nanomagnets is used in nanomagnetic logic (NML). Apart from writing and reading, nanomagnets are also clocked using external magnetic fields generated by current carrying wires. The related current ranges in mA and consumes large power. Also, the fields cannot sharply terminate at boundaries between nanomagnets that are required to be in different clock...
Conventional magnetic logic using single-domain nanomagnets face severe challenges from power consumption, during field induced writing and clocking, and from poor selectivity over the logic cells. In this paper we report a novel CMOS integrated nanomagnetic logic architecture using Magnetic Tunnel Junctions (MTJs) as elemental cells. The integration details with 22nm CMOS technology is discussed...
