Here is a link (cued to the time where it starts) of the best and most clear explanation of how core memory works. Reading & writing a bit has many steps!
Now I want to know how modern memory works with a similar level of detail.
I always felt there was something poetic about how one must destroy this kind of memory in order to read it. Observation is never passive... to observe a system is to change it... #computer#memory#history#coreMemory#cs
@futurebird Have you ever come across Ulrich Drepper's What Every Programmer Should Know About Memory?
Caveats:
No, not every programmer needs to know all of this, and some programmers need to know entirely different things about memory.
It's from 2007 so parts are slightly dated.
It entirely ignores any architecture other than x86 and any OS other than Linux.
But even with those caveats, it might be part of what you're looking for. It starts with transistors and goes up through cache coherency protocols and page tables and things like that.
