The use of NAND flash memory SSDs has definitely revolutionized the world of hard drives and storage devices for personal computers; better transfer rate, latency almost canceled IOPS values previously unthinkable, are characteristics which we can not now give up. But there is a faster memory of the Nand Flash and certainly cheaper, we speak of the "old" RAM.
The Random Access Memory is fast but has the drawback of not permanently save the data when you switch off the system. The company EverSpin however, seems to have the problem by developing the new Magnetic RAM (MRAM), a type of memory that can precisely to maintain the data when we remove current.
The company is preparing to send the first module called ST-MRAM, with a capacity of 64GB and frequency of 1600 MHz, in short, a sort of DDR3 module to be inserted in the classic slot present on motherboards. There is no info on prices, but we hope that, given the low cost of the company DDR3 does weigh too much novelty factor. source via - extremetech.com
