Which type of memory device DOES NOT require 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:
CMOS memory devices do not require a continuous base current to maintain their memory states. This makes CMOS memory devices more efficient than MOS memory devices.
Incorrect Answers:
A: 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..
C: CMOS memory devices is the correct answer.
D: CMOS memory devices is the correct answer.
