Which type of memory is primarily used as cache memory?

• RAM
• ROM
• SRAM 
• RRAM.

Answer: SRAM is the memory type that is primarily used as the cache memory.

Cache memory is the computer memory that is volatile and it is smaller in size which gives access to the processor and also stores often-used programs, information, etc. as it is not the permanent memory that’s why it makes the retrieval of data easy and also efficient.it is considered as the computer’s fastest memory and it is present in the motherboard and also embed in the processor.

It gives quick access and storage and the data which is accessed by the processor is stored in it, when the data is requested by the processor which is stored in the cache memory, then there is no need to fetch from main memory or hard disk. The cache for the hardware is also known as the processor cache, as the hardware is close to the processor core it is referred to as the primary or secondary cache memory and the primary cache is integrated directly into a processor.

There is a total 4 levels of memory which are described in the following:

Register:

At this level, the data which is quickly stored in the CPU are stored and accepted. The register which is often used is accumulator, program counter, and address register.

Cache memory:

It is level 2 of the memory whose access time is faster and the data are stored temporarily for only the fastest access.

Main memory:

Main memory is the part that is currently using my computer. The size is small and the data will remove when it is shut down.

Secondary memory:

This type of memory is opposite to the main memory which is not fast and the data stored in it is permanent.
