Question

The dynamic RAM offers __________

(a) High power consumption, large storage capacity

(b) Reduced power consumption, large storage capacity

(c) Reduced power consumption, short storage capacity

(d) High power consumption, short storage capacity

This question was posed to me by my school principal while I was bunking the class.

My question is based upon Random Access Memory in chapter Memory Devices of Digital Circuits

Answer 1

Correct answer is (b) Reduced power consumption, large storage capacity

For explanation I would say: The dynamic RAM offers reduced power consumption and large storage capacity in a single memory chip. With the availability of such high packing density memory ICs, the capacity of memory will continue to grow. However, it’s access time is more and thus operation is slow.
