Although the development of this type of flash memory is back nearly 20 years, the continued development of existing Flash memory and DRAM technology has prevented its use, or its defenders think its benefits are too obvious to come. a day when they finally fix Flash and DRAM memories and become a memory that we will all use on our PCs.
What is MRAM flash memory?
MRAM stands for Magnetoresistive Access Memory, or random magnetoresistive access memory. It's a new kind of memory that doesn't change the way you handle data, but then changes it all. And that's a start it is a non-changing memory, which means that when you turn off the PC the data will continue to be stored, in addition to having an amazing performance rate per efter, making it much cheaper to produce.
Unlike DRAM or Flash memory, data is not stored in current load or flow, but in the last things you gather two ferromagnetic discs are formed, each preserving the magnetic field.
The two discs are separated by an insulating layer, and the binary data (it and the zeros) are interpreted because one of these signals is placed in magnets, and the other moves to match the field of the other, changing from positive to negative. The MRAM memory chip is made of a mesh of this cell.
What benefits does this type of memory have compared to the present?
We've already told you about the first benefit: do not change, can hold data even when no power is involved, when you turn off the PC (according to Intel it can store data for 10 years at 200ºC). We also talked about the second benefit: its performance per lifer is much stronger (99.9%), so that's cheap to make
These MRAM memories, which are still being developed, are made using Intel & # 39; s 22 nm FFL processor, a non-efficient environment. According to the manufacturer's documentation, each MRAM bit transistor cell (0,0486 um2) is coupled to a magnetic field of only 216 x 225 nm2, meaning that the target size of "Target devices" is between 60 and 80 nm, allowing for greater variability in strength
This is especially important because at very high voltage access times are achieved, and that at 0.9V readout is only 4 digits, while at 0.8V the output voltage doubles, 8 ns.
When and how will MRAM arrive?
In a sense, MRAM is ready for mass production, so we have to wait to see how Intel intends to launch it (and hopefully it won't do as its failed Optane memory) because it hasn't yet released its system.
Yes, it's known that it's been produced for a year, or at least that's what they say in early 2019, so they have something fat in their hands, or they decide to finally get rid of it, something that doesn't seem to be behind all the effort put into its development and how it promises to work and most of all. , its profits.
