Q1:

In comparison with static RAM memory, the dynamic RAM memory has

A lower bit density and higher power consumption

B higher bit density and higher power consumption

C lower bit density and lower power consumption

D higher bit density and lower power consumption

E None of the above

ANS:D - higher bit density and lower power consumption

1. SRAM is static while DRAM is dynamic.
2. SRAM is faster compared to DRAM.
3. SRAM consumes less power than DRAM.
4. SRAM uses more transistors per bit of memory compared to DRAM.
5. SRAM is more expensive than DRAM.
6. Cheaper DRAM is used in main memory while SRAM is commonly used in a cache memory.

the bit density of SRAM is less as compared to DRAM so Option B is correct.
