The output transistor is (not surprisingly) about half of the IC die — the 7805 needs to push some current. The coolest part of the chip is a variable ... of the resistor inside, leveraging ...
Recently [Ken Shirriff] had a look inside a Ramtron FM24C64 FeRAM IC from 1999 ... In this particular FeRAM chip, there are two capacitors per bit, which makes it easier to distinguish the ...
