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.
