Pardon me, but why would you have to re-weave wires around magnetic rings? The magnetic rings are for storing data; the whole point is that you can change the data without rewiring the memory. If you have to re-wire permanent storage (e.g. program storage), that's equivalent to creating a mask ROM, which is basically just two funny-shaped sheets of conductor. There's no need for magnetic rings.
- KMag 3y agoNo, I'm not talking about magnetic core memory. Core rope memory also used little magnetic rings. https://en.wikipedia.org/wiki/Core_rope_memory https://en.wikipedia.org/wiki/Core_rope_memory input wires were energized, and they were coupled (or not) to the output wires depending on if they shared a magnetic ring (or not).
- denton-scratch 3y agoThanks! I'd never heard of rope memory.

- hinkley 3y agoBecause it’s not RAM, it’s ROM.
