Abstract

The invention relates to a storage device based on magnetic skyrmion and a method for storing information by the device, which can realize multiple replication, multi-bit storage and information screening functions of information. The memory device includes: a track including a first segment, a second segment, a third segment, and a fourth segment, one end of the first segment being connected to one end of the second segment, the other end of the second segment being connected to one end of the third segment and one end of the fourth segment, and a defect being formed on the surface of the second segment material; a write-in end arranged at the other end of the first segment and used for writing in the magnetic skyrmion; a first reading end arranged at the other end of the third segment and used for reading the magnetic skyrmion entering the third segment; and a second reading end arranged at the other end of the third segment and used for reading the magnetic skyrmion entering the fourth segment.

Description

technical field [0001] The invention relates to a storage device, in particular to a storage device based on magnetic skyrmions, and also to a method for storing information in the storage device based on magnetic skyrmions. Background technique [0002] With the advent of the information age, in order to meet the demand, the information storage devices are required to develop rapidly in terms of high density, high speed, and low energy consumption. The hard disk structure of traditional models includes: disk platters, magnetic heads, spindles and transmission shafts, etc., and data is stored in the disk platters. The writing and reading of data rely on a series of operations such as mechanical movement, that is, the magnetic head reads and writes the disk platter below it, which has obvious disadvantages such as large size. Contents of the invention [0003] Based on this, it is necessary to provide a new storage device for the above-mentioned shortcomings of the traditi...
