NEC Develops World's Fastest MRAM
Gary writes to tell us that NEC has developed a new SRAM compatible MRAM. The new memory module is capable of speeds up to 250MHz, the world's fastest to date. "MRAM are expected to generate new value and applications for future electronic devices thanks to their nonvolatility, unlimited write endurance, high speed operation, and ability to cut memory power dissipation in half. For example, these features could enable instant start up of PCs and prevent drive recorders from losing data after a sudden break in power in the future. As substitutes for system LSI-embedded SRAM, MRAM can provide even more value as they are expected to enable extremely low power dissipation of system LSIs because they can sleep when they are not in use and wake up instantly."

That is, assuming they're not manufactured by Sony.
The theory of relativity doesn't work right in Arkansas.
For small sizes (32KiB), MRAM already has a wide use in Game Boy Advance cartridges as a replacement for battery backed RAM.
I was unfamiliar with it, so I looked it up:
Magnetoresistive Random Access Memory - two magnetic plates separated by an insulator. One plate has is a permanent magnet, the other holds the temporary charge.
