Question

Dynamic memory cells use _______________ as the storage device.

(a) The reactance of a transistor

(b) The impedance of a transistor

(c) The capacitance of a transistor

(d) The inductance of a transistor

I have been asked this question in an interview for job.

This intriguing question originated from Introduction of Memory Devices in chapter Memory Devices of Digital Circuits

Answer 1

Correct answer is (c) The capacitance of a transistor

To explain: Capacitance of a transistor prevents from loss of information in a dynamic memory cell.
