Question

DRAM uses of integrated MOS capacitors as _______ instead of a flip-flop.

(a) Storage cell

(b) Memory cell

(c) Dynamic cell

(d) Static cell

The question was asked during an internship interview.

My question is from Random Access Memory in section Memory Devices of Digital Circuits

Answer 1

Right answer is (b) Memory cell

For explanation I would say: DRAM uses of integrated MOS capacitors as memory cell instead of a flip-flop. The advantage of this cell is that it allows very large memory arrays to be constructed on a chip at a lower cost per bit than in static memories.
