What makes core memory resistant to EMP?
Wouldn't the pulse change the polarizations stored in the iron cores?
> The highly irradiated port-war landscape will be unable to make use of standard silicon computer memory for centuries to come.
So we really couldn't use any silicon that was hit to make new semiconductors?
- Dangeranger 8y agoThe author’s argument is that a highly irradiated landscape would be too energetic for silicon based memory to work as it’s now designed. I’m not an EE but I’ve spoken with some engineers of early silicon systems which had to account for high energy cosmic rays flipping the bits within RAM in a random fashion. My guess is that using a solution like Hamming codes would not work when retrieving arbitrary data at a large scale.
- FPGAhacker 8y agoEcc does work for radiation hardening of storage. You can still get logic upsets in transit, between storage elements. You can either design your cells around it (high power ) or you can use a variety of redundant logic and monitors.

I've spent months chasing random crashes on another vendor's device which turned out to be solder ball alpha emission issues.
