News Memory makers join forces on MRAM

Isn't changing magnetic polarity to store data the same way a HDD works
So is the new MRam similar to a HDD platter without the spinning around part, if someone could explain where my understanding is undoubtedly wrong it would be appreciated.

 

Or, more importantly, does this mean that we are taking a HUGE step backwards in terms of memory that can again be wiped by external magnetic fields?

For example, the magnetic induction wireless charging base (oh, wait, fallen at that first hurdle) for the Nexus 5 and 7 (and Palm Touchstone) uses magnets to hold the device in place...

Granted that is for existing NAND flash devices and not future MRAM devices, but whatever you think about wireless charging, that's a bit of a setback, no?

Unless MRAM is not susceptible to external fields in which case ignore the above! ;-)

 

Magnetic storage isn't as sensitive as all that. Open up a hard drive and you'll find a big chunky neodymium magnet sitting right next to the platter. I have no idea how MRAM reacts to external fields but it can't be much of a problem or it wouldn't be considered a good contender.
