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."
