I have a very cool question to ask from you:
For some time im interested about RAM. More as a curiosity.
I've read this page: Magnetic-core_memory and also watched a couple of youtube movies to better clarify for me. And basically, one BIT of memory, is made of 1(one) ferite ring(shape), 2 wires for address at 90degree crossing through the donut hole, 1 diagonal wire that is Sense and Inhibit in the same time (sense when read, inhibit when write). The (magnetic) polarity of the ferrite gives the state of the Bit, if its right is On, if is left is Off. This is also a destructive readout = when the read action is performed, it is erased in the same time. When not being read or written, the cores maintain the last value they had, even if the power is turned off. Therefore they are a type of non-volatile memory.
But this is A TYPE of memory bit and is OLD technology. I want to know how Modern Memory are made of. Understand my question well. Im not interested in how is accessed/addressed, but how is built and what material really stores the electric charge? From my general knowledge, in modern microcips are transistors, diodes, resistors and capacitors, all in order of millions inside the cip circuit . But my question is not the circuit, but what is keeping the charge? I always presumed, because i didnt find anything on this subject good enough, maybe its the circuit itself? I always assume there may be some capacitors that keep the charge inside the circuit of the memory cip. How would look the simplest circuit ? (if it turns out to be the circuit or the capacitor holding the charge as i imagine). The basic circuit.
Thank you !
