摘要:

磁畴壁(DW)已经被广泛研究用于未来的存储器和计算系统。然而,能量效率和稳定性成为基于DW的系统的两个主要挑战。在这封信中,我们首先提出利用skyrmions作为芯片上和芯片间的互连基于DW的系统,由于拓扑稳定,小尺寸和超低的脱钉电流密度。在所提出的技术中,数据以DW的形式处理,但以skyrmions的形式传输。通过连接一根宽的和一根窄的磁性纳米线,可以在物理上实现Skyrmion和DW对之间的可逆转换。我们所提出的技术可以实现高度紧凑,鲁棒性和节能的片上和芯片间互连的DW为基础的系统,使系统能够同时利用DW和skyrmion。

英文摘要:

Magnetic domain-wall (DW) has been widely investigated for future memory and computing systems. However, energy efficiency and stability become two major challenges of DW-based systems. In this letter, we first propose exploiting skyrmions as on-chip and inter-chip interconnects for DW-based systems, owing to the topological stability, small size and ultra-low depinning current density. In the proposed technique, data are processed in the form of DWs but are transmitted instead in the form of skyrmions. The reversible conversion between a skyrmion and a DW pair can be physically achieved by connecting a wide and a narrow magnetic nanowire. Our proposed technique can realize highly compact, robust and energy-efficient on-chip and inter-chip interconnects for DW-based systems, enabling the system to take advantages of both the DW and skyrmion.
