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. ...
Sounds like super conduction would be involved somewhere.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)'. ...
