Correct Answer - Option 4 : 1, 2 and 4

SRAM: The SRAM memories consist of circuits capable of retaining the stored information as long as the power is applied i.e. it requires constant power. SRAM memories are used to build cache memory. It can retain stored data indefinitely and it can be implemented as a flip flop circuit to store one bit of information.

DRAM: DRAM stores the binary information in the form of electric charges that applied to capacitors. The stored information on the capacitors tends to lose over a period of time and thus the capacitors must be periodically recharged to retain their users. The main memory is generally made up of DRAM chips.

Differences between SRAM and DRAM:

SRAM

DRAM

It has lower access time, so it is faster compared to DRAM

It has higher access time, so it is slower than SRAM

It is costlier than DRAM

It costs less compared to SRAM

As it requires a constant power supply, consumes more power

It offers reduced power consumption due to the fact that the information is stored in the capacitor

Due to complex internal circuitry, less storage capacity is available compared to the same physical size of the DRAM memory chip.

Due to small internal circuitry, large storage capacity is available

It has low storage density

It has a high storage density
