Hi Learner! Today, we are going to reveal about many advantages of SRAM and its disadvantages as well; involving with various drawbacks and benefits of SRAM (Static RAM) with ease. We make ensure that at the end of this article, you will definitely fully ware about pros and cons of SRAM without getting any hindrance.
SRAM stands for “Static Random Access Memory”, and it is also simple types of Random Access Memory that helps to store all data with using of static technique. Static RAM is able to retain all information into static form until power supply is turn off, so due to this nature this memory is known as volatile memory.
SRAM is totally different to DRAM because DRAM requires regularly refreshing data that is store in the memory. So, SRAM’s speed is fastest to DRAM as well as it consume less power to DRAM.
What Are The Advantages And Disadvantages of SRAM?
From this article, we will guide you about cover various major advantages and disadvantages of SRAM | drawbacks and benefits of SRAM (Static RAM) with ease. So, you should be known about before using of SRAM on your computer system.
Advantages of SRAM over DRAM
There are some benefits of SRAM over dynamic RAM, as follow them:

- No require periodically refreshment circuit.
- Less power consumption than DRAM
- Great Performance to DRAM
- Good reliability compare to Dynamic RAM
- Less idle time during power consumption
- It is used as cache memory in computer systems
Disadvantages of SRAM over DRAM
There are some limitations and drawbacks of SRAM, such as:
- More expensive to DRAM
- High density
- SRAM is not used for main memory.
- SRAM is volatile memory in nature.
- SRAM is also used to construct small size cache memory.
- More power consumption while performing their tasks.
- It has very complex structure.
- Low storage capacity to DRAM
Applications & Uses of SRAM
Static RAM is mostly used in different areas such as –
- Modern Electronics Equipment
- Automobile Equipments
- Computer Cache Memory
- Digital to Analog Converter on a video card
- Digital Cameras
- Cell Phones
- CPU register files
- Hard disk buffers
- Router buffers
- LCD Screens
- Medical Equipments
- Computing Applications
Main objective of using the static RAM is to make Cache Memory. Static Ram is more expensive because it is made with using of much complicated structure, and its complexity is also limited for storing amount of data into one chip. Due to this, SRAM chips have not ability to hold much data compare to DRAM. So, SRAM is used mostly in to small size applications like as CPU cache memory and hard drive buffers, compact discs (CD’s), printers, modem, routers, digital versatile discs (DVD’s) and digital cameras.
In SRAM, All data has been stored in flip-flop. Flip-flop contains the every bit of this Ram. Flip-flop uses 4-6 transistors for making a memory cell and its circuit do not need to refreshment continuously. SRAM helps to store every bit with using of bistable latching circuitry, and typically it used six MOSFET to store every memory bit but extra transistor become at smaller nodes.
SRAM holds a bit of data on 4 transistors with using of 2 cross coupled inverters, and it has two stable states like as 0 and 1. Due to read and write operations, other two access transistors are used to handle the availability for memory cell. It needs 6 MOFSET (metal-oxide-semiconductor field-effect transistor) to hold per memory bit. MOFSET is also one type of SRAM chip, and other is bipolar junction transistor. Bipolar junction transistor’s speed is fastest but it uses much power.
Now, i hope that you have completed educated about major advantages and disadvantages of SRAM | drawbacks and benefits of SRAM (Static RAM) with ease.
