This article is about how to solve the problem of MRAM lifespan. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

MRAM is a kind of nonvolatile magnetic random access memory. It has the high-speed read and write ability of SRAM memory chip, as well as the high integration of dynamic DRAM, and can be repeated for unlimited times. The basic principle of MRAM is similar to that of a hard disk drive. Like storing data on a hard disk, the data is stored as 0 or 1 on the basis of magnetic quotient. The data it stores is permanent, and the magnetic data will not be changed until it is affected by an external magnetic field. Because of the use of magnetic recommended storage data, MRAM has greatly reduced the cost of supporting children. This article focuses on selling Everspin MRAM and other memory chip suppliers to introduce how to solve the problem of MRAM life.

In the high-density MRAM module, we will encounter the irregular vortex of the magnetic medium, which causes the aging of the magnetic pole and even leads to reading and writing errors. That is to say, the life and stability of MRAM will face a severe test with the increase of MRAM capacity. For this reason, the VERTICAL RING GMRCELLS technology (vertical surround giant magnetoresistive unit) is ordered in the face of danger, and it is obvious that VRGC makes the magnetosphere soft and hard. We should not underestimate this simple change, such a vertical arrangement of giant magnetoresistance will basically eliminate the irregular whirlpool, effectively solve the aging problem of MRAM. In addition, in order to enhance the stability of MRAM and avoid reading and writing errors, VRGC technology adds an additional pair of parallel character lines to each basic unit, which is similar to the check function commonly used in server memory.

The above is how to solve the problem of MRAM life. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
