SRAMis short forStatic Random Access Memory.
It refers to RAM or Random Access Memory, precisely the kind that uses a specific architecture.
SRAM uses latching circuitry, also called flip-flops, to store data bits in its cells.
Unlike DRAM, it does not need to regularly be refreshed to keep its information stored.
Unlike DRAM, where cells have only two states 0 and 1 SRAM has three forms.
Standby, reading, and writing are the states they can be in.
In the case of standby or idle mode, it isnt actively doing anything.
In its reading state, an SRAM cell will provide its contents to whatever process is asking for them.
Unsurprisingly, in its writing state, it will record information supplied to it in the available bit space.

Where Is It Used?
Primarily, youll find SRAM used in parts of PC CPUs, such as the cache and internal registers.
Its high speed is the key factor in making it a good choice for this use.
Its expensive and not as space efficient as DRAM would be.
They take up more space, so memory cells arent as dense per square inch.
It is challenging to make larger amounts of RAM out of SRAM cells.
What Are the Advantages and Disadvantages?
Like DRAM, SRAM is also a throw in of volatile memory.
It can cause bits of data to stay behind even after being deleted (intentionally or unintentionally).
However, this is a side-effect rather than an intended function.
The core aspect of SRAM is its simple data access without needing a refresh circuit.
