Abstract

A system and method for a logic device is disclosed. A plurality of nanotracks are disposed over a substrate, along a first axis, with at least a left nanotrack, a right nanotrack and a middle nanotrack disposed between the left nanotrack and the right nanotrack. At least one connector nanotrack is disposed to connect two adjacent nanotracks. An input value is defined at a first end of the plurality of nanotracks by selectively nucleating a skyrmion at the first end. Presence of the skyrmion is indicative of a first value and absence of the skyrmion indictive of a second value. The nucleated skyrmion moves towards the second end of the nanotrack when a charge current is passed along the first axis. The presence of the skyrmion sensed at the second end of the middle nanotrack indicates an output value of the first value.
