Current-induced domain wall motion in racetrack memory promises energy-efficient analog computation using compact magnetic nanowires. This paper explores the feasibility of data converters based on current-induced domain wall motion and introduces an n-bit ADC using n racetrack magnetic nanowires. With each magnetic nanowire having a different configuration granularity, an n-bit binary or gray code...
Security is a key concern in today's mobile devices and a number of hardware implementations of security primitives have been proposed, including true random number generators, differential power attack avoidance, and chip-ID generators [1-4]. Recently, physically unclonable functions (PUFs) were proposed as a secure method for chip authentication in unsecure environments [5-7]. A PUF is a function...
