SRAM VS DRAM: What Is the Difference Between Them?

What Is SRAM and what is DRAM?

Whats the difference between them?

Both SRAM and DRAM belong to different types of RAM.

And before talking about SRAM vs DRAM, lets get some information on SRAM and DRAM.

What Is SRAM?

First of all, what is SRAM?

It is short for staticrandom-access memory, belongs to a key in of semiconductor RAM.

And the data is stored using the six transistor memory cell in SRAM.

SRAM is often used as acache memoryfor the processor (CPU).

To learn more information about SRAM, read this post Introduction to SRAM Memory (Static Random-Access Memory).

DRAM is often used in digital electronics.

To learn more information about DRAM, read this post Introduction to DRAM Memory (Dynamic Random-Access Memory).

Speaking of SRAM vs DRAM, their capacity and density need to be compared.

Due to its structure, SRAM requires more transistors than DRAM to store a certain amount of data.

Power consumption also needs to be mentioned when talking about SRAM vs DRAM.

Generally, SRAM modules consume less power than DRAM modules.

The refresh current is several orders of magnitude larger than the low SRAM standby current.

Therefore, SRAM is used in most portable and battery-powered devices.

Nevertheless, the power consumption of SRAM does depend on how often it is accessed.

If SRAM is used at a lower speed, the power consumed during idle time is almost negligible.

On the other hand, at higher frequencies, SRAM consumes as much power as DRAM.

Now we talk about DRAM vs SRAM for price.

SRAM is much more expensive than DRAM.

The most common utility of SRAM is as a cache for the processor (CPU).

The most common tool of DRAM (such asDDR3) is volatile storage in computers.
