Problems solved by technology

[0003] In the current track memory, since the magnetic nanotubes in it need to reserve memory cells without written skyrmions at one end across the read magnetic tunnel junction, the read magnetic tunnel junction has difficulty in completing reading and writing. The skyrmion in the skyrmion storage unit can continue to push the read skyrmion forward, avoiding the problem that the stored data disappears and cannot be reset, but this reduces the storage density of the magnetic nanotube

Abstract

A racetrack memory includes a magnetic nanotube, a first write magnetic tunnel junction, a first read magnetic tunnel junction, and a memory connected to the first write magnetic tunnel junction and the first read magnetic tunnel junction for temporarily storing storage data obtained through the first read magnetic tunnel junction, and the first write-in magnetic tunnel junction is used for writing the second write-in magnetic tunnel junction into the plurality of first storage units again in the form of skyrmion. By introducing the memory, the stored data can be reset, and the storage densityof the magnetic nanotubes is further improved.

Description

technical field [0001] The invention relates to the field of memory, in particular to a race track memory, a reading and writing method thereof, and a race track storage device. Background technique [0002] Magnetic random access memory (MRAM) is a new type of non-volatile random access memory based on the tunnel magnetoresistance (TMR) of the magnetic tunnel junction. The number of times, and power consumption have appropriate performance, so it is considered by the industry as a potential memory for building the next generation of non-volatile cache and main memory. [0003] In the current track memory, since the magnetic nanotubes in it need to reserve memory cells that have not written skyrmions at one end across the read magnetic tunnel junction, the read magnetic tunnel junction has to be read and written. The skyrmion in the skyrmion storage unit can continue to push the read skyrmion forward, avoiding the problem that the stored data disappears and cannot be reset,...
