Power consumption of dynamic RAMs is more than that of static RAMs.

Gate, density of dynamic RAMs is higher than that of static RAMs.

Dynamic RAMs require a memory refresh cycle after each memory read cycle.

Main memory of a general purpose computer system is usually built using dynamic RAMs.

Direct mapped caches do not need a cache block replacement policy, whereas fully associative caches do.

In a fully associative cache, the full address is stored alongside the data block.

A direct mapped cache is organized according to an 'index', and the'tag' part of the memory address is stored alongside the data block.

Direct mapped caches may produce more misses if programs refer to memory words that occupy a single tag value.
