In SRAM, the data is stored in transistors, In DRAM, the data is stored in capacitors.
SRAMs are used in cache memory, while DRAMs are used in main memory.
Here are the major difference between SRAM and DRAM.
RAM stands forRandom Access Memoryits a hardware equipment generally located motherboard of a computer or laptop.
Both SRAM and DRAM have their own advantages and disadvantages compared to the other.
Lets find outhow an SRAM is different from a DRAM.
These differences occur due to the difference in the technique which is used to hold data.
DRAM needs refreshing, whereas SRAM does not require refreshing the memory cell.

What is DRAM (Dynamic Random Access Memory)?
DRAM stands for dynamic random access memory.
Its widely used as the main memory for a computer system.
DRAM takes 1 transistor and 1 capacitor to store 1 bit.
As we know a capacitor is like a container that stores electrons.
To do this, the memory controller reads the data and then rewrites it.
This is called refreshing and occurs thousands of times per second in a DRAM chip.
Because of the need to constantly refresh data, which takes time, DRAM is slower.
The most common tool of DRAM such as DDR3 is volatile storage for computers.
What is SRAM (static random access memory)?
SRAM stands for static random access memory.
It is normally used to build very fast memory known as cache memory.
SRAM takes 6 transistors to store 1 bit and its much faster compared to DRAM.
This makes static RAM significantly faster than dynamic RAM.
Therefore you get less memory per chip, and that makes static RAM a lot more expensive.
Its more Faster:Because SRAM does not need to refresh, it is typically faster.
The most common software of SRAM is to serve as a cache for the processor (CPU).
In processor specifications, this is listed as L2 cache or L3 cache.
Due to this key difference, other differences arise too.
Dynamic RAMs have a simple internal structure in comparison to SRAMs.
SRAM vs dram speed
SRAM is typically faster than DRAMsince it doesnt have refresh cycles.
SRAMs are used in cache memory, while DRAMs are used in main memory.
Due to the use of capacitors, DRAM requires to be refreshed periodically.
DRAMs are less expensive and slower than SRAMs.
FAQ:
Which RAM is better SRAM or DRAM?
SRAM outperforms DRAM in terms of speed and cost.
DRAM provides more storage capacity than SRAM.
Cache memory uses SRAMs, whereas main memory uses DRAMs.
SRAM is used for the smaller and faster cache memory.
The disadvantage of dynamic RAM over static RAM is?
SRAM vs DRAM which is faster?
SRAM is comparatively faster than DRAM.
Why is RAM called volatile memory?
RAM store working data until the PC is running and loses its content when the power is turned off.
This means it temporarily stores data until power is on thats why its called volatile memory.
