How do you know that it is a inductor? Can you tell me why it is not capacitor?V=Ldi/dt
L=?
OK voltage across the inductor will be zero if the current throw it remains constantbecause di/dt is a constant with V=constant
So how much is L?
DRAM (all large memory) also relies on a minute capacitor to store charge, but only for a few miliseconds before the charge is refreshed.
And before EPROM there was PROM where you blasted links. Although rudimentary by modern standards, PROMs were a game changer when they first came out.
Yes, ferroelectric; I had forgotten about that.

Those were the days. You had to work really hard to realise a function. It was a constant tug between size, power consumption, and cost. ...
I remember during one of my many visits to the Smithsonian museum in DC (mid-80's). I was wandering around in the computer section and spied an unidentified device.
It was an approximately 4"X6"X2" block of aluminum with an odd looking PCB mounted on its top.
I asked a docent what it was. He responded that it was an experimental, 2k memory "brick" from IBM.
It had two small port tubes in the Al block and I asked if he knew their purpose. He said they were for the liquid nitrogen used to cool the "brick"... .
It's pretty neat, for sure. The "new" Udvar-Hazy (Smithsonian National Air and Space Museum's annex at Washington Dulles International Airport) is also remarkable. It has a whole section devoted to diesel aircraft engines - none of which were ever actually used in an aircraft .... I would love to visit the Smithsonian. ...
Did not know this acronym. Thanks, spec.... A handy acronym is CIVIL which stands for, 'with a capacitor the current leads the voltage (by 90 degrees) and with an inductor voltage leads current (by 90 degrees)'. ...
