Abstract
Nanomagnetic logic is a recent technology used in electronic devices and systems. The current challenge in circuit miniaturization has prompted a move away from the traditional metal-oxide-semiconductor technology. Nanomagnetic logic-based devices have no leakage current, and they are also non-volatile. In this paper, we propose run-time reconfigurable layout designs for the logic gates, and to show the applicability of the logic gates, we implement a single-bit comparator design. For the logic gate designs, we use slant-edge nanomagnets of different shapes as inputs. The proposed layout designs are verified using the MuMax3 micro-magnetic simulation tool, and results are compared with a previous approach. The implementation of a single-bit comparator design can significantly reduce the number of nanodots required, typically by \(\sim\)50–80%, as well as the area occupancy, which can be reduced by \(\sim\)56–99%.
