Freescale MRAM - an in-depth examination

Here's an interesting examination of Freescale's MRAM by SemiSerious.

MRAM will not replace DRAM because it is slower, therefore The "instant-on" computer is not around the corner, but MRAM can boot operating systems or other code faster than present-day NOR flash.

The bottom line may be evolution — not revolution as Freescale's new MRAM device seems most suited to critical military and space applications where MRAM has already been deployed at lower resolutions. MRAM is very likely to start to replace NV-SRAM since it must be cheaper to produce a more or less standard die in a standard package than to start adding batteries to the mix.
