چکیده
Magnetic skyrmions are promising candidates for logic-in-memory applications, intrinsically merging high density non-volatile data storage with computing capabilities, owing to their nanoscale size, fast motion, and mutual repulsions. However, concepts proposed so far suffer from reliability issues as well inefficient conversion of magnetic information electrical signals. In this paper, we propose a device which exploits skyrmion confinement channeling using anisotropy energy barriers achieve reliable synchronous shift in racetracks combined cascadable reprogrammable logics relying purely on interactions. The combines racetrack register based confined nanodots Full Adder (FA) gates. designed FA is can also be used perform simple logic operations such AND, OR, NOT, NAND, XOR NXOR. monolithic design the gate absence any complex contacts makes ideal integration conventional CMOS circuitry.

0272-1732/00/$10.00 2000 IEEE Traditionally, undergraduates in electrical and computer engineering study the design and implementation of a simple computer and then develop their own designs. In recent years, computer design courses have for the most part taken a simulation-only approach. Rapid prototyping techniques and a new generation of large field-programmable logic devices (FPLDs) enabl...

Advances in programmable logic devices' architectures are making PLDs suitable for a plethora of applications. The devices now find use in state machines and other highly sequential circuits. In the past two years, bipolar PLD operating speeds have doubled, and emerging CMOS PLDs offer four times the circuitry per chip than the older bipolar versions offered. CMOS PLDs also offer lower operatin...
