Question

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

Answer 1

Answer: (D)

Higher bit density and lower power consumption

In comparison with static RAM memory, the dynamic RAM memory has a Higher bit density and lower power consumption.

A flip-flop for a memory cell takes 4 or 6 transistors along with some wiring, but never has to be refreshed. This makes static RAM significantly faster than dynamic RAM. However, because it has more parts, a static memory cell takes a lot more space on a chip than a dynamic memory cell.

SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which stores bits in cells consisting of a capacitor and a transistor, SRAM does not have to be periodically refreshed.

A capacitor stores electrons in computer memory cells. The memory must then be refreshed or flip-flopped. Your computer probably uses both static RAM and dynamic RAM at the same time, but it uses them for different reasons because of the cost difference between the two types.
