Which type of memory device requires a continuous base current to maintain their memory states?

A.
MOS memory devices

B.
CMOS memory devices

C.
Both of the above

D.
None of the above

Explanation:
MOS memory devices require a continuous base current to maintain their memory states.
This requirement leads to a net transfer loss from emitter to collector, which can run into vast quantities when gigabytes of RAM are being used.
Incorrect
Answers:
B: CMOS memory devices do not require a continuous base current to maintain their memory states.
C: MOS memory devices is the correct answer.
D: MOS memory devices is the correct answer.
