Abstract

The invention relates to a storage device based on magnetic skyrmions and a method for storing information by the device, which can realize multiple copying of information, multi-bit storage and information screening functions. The storage device includes: a race track, including a first section, a second section, a third section and a fourth section, one end of the first section is connected to one end of the second section, and the other end of the second section is connected to One end of the third segment and one end of the fourth segment have defects formed on the surface of the material of the second segment; the writing end is provided at the other end of the first segment for writing magnetic Skyrmions; the first reading end is located at the other end of the third section for reading the magnetic skyrmions entering the third section; the second reading end is located at the end of the third section The other end is used to read the magnetic skyrmions that go into the fourth segment.

Description

Magnetic skyrmion-based storage device and method for storing information in the same technical field The present invention relates to memory device, relate in particular to a kind of memory device based on magnetic skyrmion, also relate to a kind of Methods for storing information in magnetic skyrmion-based memory devices. Background technique With the advent of the information age, in order to meet the needs, high-density, high-speed, Low energy consumption and other aspects of rapid development requirements. The traditional model hard disk structure includes: disk platter, magnetic head, spindle and transmission axis, etc., the data is stored in the disk platter. The writing and reading of data relies on mechanical movement, that is, the magnetic head A series of operations such as reading and writing are performed by using disk platters, which has obvious disadvantages such as large size. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to pro...
