higher bit density and higher power consumption

Option D

Answer 1

option B

Since SRAM uses several transistors per bit of memory versus DRAM, which uses one transistor and capacitor per bit, so SRAM higher dense than DRAM

The dynamic term indicates that the charges are continuously leaking even in the presence of continuous supplied power that is the reason it consumes more power.On the other hand, there is no issue of charge leakage in the SRAM.

Power consumption is higher in DRAM than SRAM. SRAM operates on the principle of changing the direction of current through switches whereas DRAM works on holding the charges.

Comments

SRAM has lower bit density than DRAM. None of the options are correct.

yes DRAM has HIGHER BIT DENSITY & HIGHER POWER CONSUMPTION.

OPTION D should be the answer.
