  The recent demonstration of current-driven magnetic domain wall logic [Z. Luo
et al., Nature 579:214] was based on a three-input logic gate that was
identified as a reconfigurable NAND/NOR function. We reinterpret this logic
gate as a minority gate within the context of threshold logic, enabling a
domain wall threshold logic paradigm in which the device count can be reduced
by 80%. Furthermore, by extending the logic gate to more than three inputs of
non-equal weight, an 87% reduction in device count can be achieved.
