SRAM is a type of RAM (Random Access Memory) that is able to retain data bits in its memory a long as power is being supplied. Now, here we are going to cover about what is static and its full form; involving with different types of SRAM with ease. After completing this post, we make ensure that you will definitely completely aware about What is SRAM and its Types without getting any Obstacle.
What is SRAM?
Definition – Full form of SRAM is “Static Random Access Memory” in Computer industry. SRAM is also simple types of RAM (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.

Let’s Get Started!!
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.

Types of SRAM (Static RAM)
There are different types of SRAM, such as –
Non-Volatile SRAM:
Non-volatile SRAM is capable to store all information when power supply gets turn off.
Pseudo SRAM:
Pseudo SRAM uses the self refresh circuit, but it is slow speed to static RAM.
Static RAM is divided into two parts according to its functionality
Asynchronous:
In which, Address transition has all control of data in and data out, and it contains the independent of clock frequency.
Synchronous:
In which, all control signals, data, and address are linked with the clock signals.
Characteristics of SRAM
It occupies less storage space as compare to DRAM.
Less power consumption to DRAM
Usage: level 1 or level 2 cache
Cycle time is lesser than to DRAM because SRAM doesn’t need to pause in between accesses.
SRAM is a type of RAM (Random Access Memory) that is able to retain data bits in its memory a long as power is being supplied. Static RAM doesn’t have this need that outcome result in the better performance with low usage of power.
What is SRAM used for?
SRAM is primary used in the computer’s cache memory like as processor’s L2 or L3 cache.
What is the purpose of SRAM?
The main objective of designing the SRAM is to complete two needs: first is to serve a direct interface along with CPU as speeds not attainable by DRAMs and seconds is to replace DRAMs in the systems that need with lower power usage.
Why is SRAM used for cache?
SRAM contains the constant power supply, so it doesn’t need to be refreshed in order to keep remember the data being stored in it.
What is the size of SRAM?
The storage capacity of SRAM is 1MB to 16MB
What are the different types of SRAM?
There are two different types of SRAM like as Non-Volatile SRAM and Pseudo SRAM. Further, Static RAM is divided into two parts according to its functionality such as Asynchronous and Synchronous.
What does SRAM stand for?
SRAM stands for ‘Static Random Access Memory’ in the computer industry. SRAM is also simple types of RAM (Random Access Memory) that helps to store all data with using of static technique.
What are the examples of SRAM?
SRAM is widely used in computer for enhancing its speed, for example it may be part of a RAM digital-to-analog converter (RAMDAC) on a video or graphic card of computer.
What are the common characteristics of SRAM?
Cycle time is lesser than to DRAM because SRAM doesn’t need to pause in between accesses.
Low consumption of power
Why SRAM is called SRAM?
SRAM is an acronym comprising the names of its founders, Scott, Ray, and Sam, (where Ray is the middle name of the company’s first CEO, Stan Day).
