Cache Memory Explained

In this video, what is cache memory in CPU, is explained.

So, in this video, we will see, what is Cache memory in computers, what is the importance of this cache memory, what are the different levels of cache memory that we find inside our computers or laptops and what is the typical size of this cache memory in our computers and laptops.

Cache Memory:
Cache memory is the small size of RAM inside the processors. This cache memory is SRAM (Static RAM) unlike the DRAM (Dynamic RAM) which we find in normal RAM. This SRAM is quite fast compared to DRAM.

In computers, we find different levels of cache memory.
Level 1 Cache:
This is fastest among all Caches available in the computer processors. But very small in terms of the size. Typically few KBs.
It is embedded inside the CPU itself and all the cores inside the CPU have their individual L1Cache.

Level 2 Cache:
This L2 cache could be inside the CPU or it could be outside the CPU. It could be shared among all the cores or it could be individual for each core. It is larger in size compared to L1 cache but it is slow in comparison to L1 cache.

L3 Cache:
This L3 cache is not available in all the processors, but in some high-end processors, it is available to enhance the performance of the L1 and L2 cache. It slowest among all cache memory. It is outside the CPU and shared between the all the cores of the CPU.
