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: Option D
Solution (By Examveda Team)
In comparison with static RAM (SRAM) memory, the dynamic RAM (DRAM) memory has:Higher bit density: DRAM can store more data in the same physical space compared to SRAM because it uses a single transistor and a capacitor per bit, whereas SRAM uses multiple transistors per bit.
Lower power consumption: DRAM generally consumes less power than SRAM when storing data because it requires less hardware per bit. However, DRAM needs to be periodically refreshed to maintain the data, which does consume power, but overall it is still less than SRAM's constant power requirement.
Therefore, the correct answer is Option D: higher bit density and lower power consumption.

wrong
Ans should b (B)
This is wrong. SRAM has lower power consumption. Because there is a need for power refresh frequently to keep the bit in the capacitor.
wrong answer, static ram have less power consumption
