Abstract

An on-chip information transmission device based on magnetic skyrmion and consists of a magnetic skyrmion signal generator, a magnetic nano track used for magnetic skyrmion signal transmission and a signal reading device used for detecting magnetic skyrmion, wherein the magnetic skyrmion signal generator is positioned at the sending terminal of the magnetic nano track, the magnetic skyrmion signal reading device is positioned at the receiving terminal of the magnetic nano track, and the magnetic nano track can play a role of connecting the whole device; during operation, the magnetic skyrmion signal generator converts a signal required to be transmitted into skyrmion on a magnetic nano-ribbon, and after the skyrmion is transmitted by the magnetic nano track, the magnetic skyrmion signal reading device at the tail end reads the signal and recovers the signal into a required electrical signal. The on-chip information transmission device overcomes the shortcoming that step-by-step magnification is required for signal transmission in a traditional circuit, and can greatly reduce energy consumed by signal transmission in a chip to realize low-power-consumption design.

Description

technical field [0001] The invention relates to an on-chip information transmission device based on magnetic skyrmions, which aims at reducing the power of on-chip information transmission, and belongs to the technical field of new magnetic devices. Background technique [0002] With the rapid development of semiconductor technology and the continuous improvement of chip operating frequency, the sharp increase of chip power consumption has become an important factor restricting chip performance. On the other hand, the rise of mobile platforms has also put forward higher requirements for chip power consumption. In recent years, the magnetic skyrmions discovered in research have been proven to be used as carriers of binary information in chips, and chip designs based on magnetic skyrmions are expected to greatly reduce chip power consumption. [0003] Skyrmions (skyrmions) were originally particle-like topologically stable field structures discovered by nuclear physicist Tony...
