论文摘要
磁性天际是有希望的逻辑中逻辑应用程序的候选者，由于其纳米级的大小，快速运动和相互排斥，将高密度的非挥发性数据存储与计算能力合并。但是，到目前为止，提出的概念遭受了可靠性问题以及将磁信息转换为电信号的效率低下的概念。在本文中，我们提出了一种内存设备，该设备使用各向异性能屏障来利用Skyrmion限制和引导，以实现可靠的数据存储和赛车场中的可靠数据存储和同步移位，并结合纯粹依赖于磁性相互作用的壳牌和可重编程的逻辑。该设备将基于局限于带有完整加法器（FA）门的纳米模特中的天际矩阵结合了一个赛车位移寄存器。设计的FA是可重编程的且可覆盖的，也可用于执行简单的逻辑操作，例如和或不nand，nand，xor和nxor。逻辑门的整体设计和缺乏任何复杂的电气接触使该设备与常规CMOS电路集成在一起。
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 as inefficient conversion of magnetic information to electrical signals. In this paper, we propose a logic-in-memory device which exploits skyrmion confinement and channeling using anisotropy energy barriers to achieve reliable data storage and synchronous shift in racetracks combined with cascadable and reprogrammable logics relying purely on magnetic interactions. The device combines a racetrack shift register based on skyrmions confined in nanodots with Full Adder (FA) gates. The designed FA is reprogrammable and cascadable and can also be used to perform simple logic operations such as AND, OR, NOT, NAND, XOR and NXOR. The monolithic design of the logic gate and the absence of any complex electrical contacts makes the device ideal for integration with conventional CMOS circuitry.
