Disadvantage of dynamic RAM over static RAM is
Correct Answer: C
Question 10 Explanation:
→ Dynamic random access memory, implies, this form of memory technology is a type of random access memory. It stores each bit of data on a small capacitor within the memory cell. The capacitor can be either charged or discharged and this provides the two states, “1” or “0” for the cell.
→ Since the charge within the capacitor leaks, it is necessary to refresh each memory cell periodically. This refresh requirement gives rise to the term dynamic – static memories do not have a need to be refreshed.

Higher power consumptions
Variable speed
need to refresh the capacitor charge every once in two milliseconds
higher bit density
