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.
The timestamped link for the different topics is given below:

This video will be helpful for all to understand, what is cache memory (CPU Cache) in computers and laptops.

The other reasons L1/L2/L3 cache is smaller than RAM are power consumption and space. Since each bit in SRAM is made of a 6 transistors and 1 inverter while DRAM is at most a transistor and a capacitor(which needs to be refreshed several times in single clock cycle), SRAM draws more power. For the same reason, SRAM is much bigger in size than DRAM. Remember that L1 is collocated on the same chip as other cores in a tiny space so it must balance the space and power consumption.

[@ALLABOUTELECTRONICS]

Very True John 👍

[@shivamgahoi]

@@ALLABOUTELECTRONICS your videos are superb..its true that SRAM consumes more power than dram because of all reasons specified above. However, by mistake, you wrongly said "SRAM consumes less power than dram but when these rams operate at high frequencies they consume comparable power" in your video titled "SRAM vs DRAM".... I hope you will correct it....pls notify me after correction....thank you

[@vomeshdewangan4760]

Thanks, you too bro🤗

[@rafikhan7779]

it was a brilliant presentation do not listen to the people who are criticizing you accent, you did your level best and i understood the whole concept very well !!!

[@tuuuujack184]

Maybe thats because you are also some sort of asian.

@@tuuuujack184 Clearly english is not our mother tongue nor we have any emotional attachment to it. Say in future China becomes no. 1 then we won't mind dumping english and learn chinese.
So, go teach the values of english language to those who care. We're not one of them.
