What is the next generation memory "MRAM" to replace DRAM

Currently, the information stored in the memory used in the PC, so-called DRAM, disappears when the power is turned off. It is so-called volatile memory. However, development of memory that does not disappear even when the power is turned off is progressing, and finally it came one step before practical use. That name is called "MRAM".

With this memory, even if the power is turned off during document creation in Excel or Word, it will be possible to return to the point just before it falls. In addition, the speed and capacity are higher than before, and the power consumption further decreases. Just a dream memory.

Details are as follows.

According to this article, a company called "Freescale Semiconductor Inc.", which spun off all the assets of the semiconductor sector from Motorola, Inc. in the United States, will eventually begin practical application of MRAM.

Basically, the recording mechanism is fundamentally different from MRAM and normal DRAM and so on. In brief, MRAM records with the same magnetism as the hard disk. Therefore, it is non-volatile and the information in it does not disappear.

Most current semiconductor memories such as DRAM and SRAM have the drawback of "volatility".
If you turn off the power switch, all memory memories will be lost.

Often I experience that the word processor and spreadsheet data that I took half day and it took a day to disappear in an instant due to personal computer hangups and blackouts.

If the memory is nonvolatile, there is a high possibility that valuable data will be saved even in such a case.

How much merit there is compared with the existing memory is that writing and reading are at the same level as SRAM, a large capacity equivalent to that of DRAM can be secured, while having nonvolatility such as fresh memory, low consumption It is electric power. The disadvantage is cost.
