MRAMs, which Freescale claims can store data forever, are moderately fast and don’t require a constant electrical current to retain data, the Journal reports. They’re produced by combining silicon and permanently magnetized materials, and they store data by altering magnetic states and managing resistance to the flow of the chips’ electrical current, according to the Journal. In addition to the fact that MRAMs don’t need a constant electrical current, they’re much faster than DRAMs, and they’re comparable to some SRAMs, Bob Merritt, a Semico Research analyst, told the Journal.

Sadana said MRAM technology is particularly suited to applications where speed and long-term data storage are key elements, and his firm will continue to develop the technology with these types of uses in mind, though it may commission outside companies for assistance, according to the Journal.


Where I work, we spend a small but significant amount of time writing and debugging code to write data to Flash. And we have to keep writing that code over and over again, because everyone's Flash write procedures are a little different. Speed of write isn't such a big deal to us. But a chip that we can write to like an SRAM, but retains data like Flash? This is pretty cool tech...

And unlike a lot of cool tech we hear about that's "just on the horizon", you can buy MRAM chips today.

Yay, magnetic core memory is back!

I think this is really neat. For a PC you'll have a processor, maybe a level 1 cache, and banks and banks of mram that store everything, hibernate instantly, and are solid state. You might throw in a magnetic hard drive for storing really big files.

hard drives become obsolete, and all storage is used by static RAM or some derivitive therein.

One of our customer's husbands works at Seagate, and she said that his job is in jeopardy in the next few years because they're hitting a physical limitation on the amount of data that can be stored on a hard drive. She also mentioned that they're working on a new technology that will double the expected capacity of current hard drive technology, but could not comment further. :)

I think that memory will replace hard drives soon, but it's a matter of how soon, and how cheap.
