Answer 2

Answer:

The Cache memory is also Random Access Memory but it is a special kind of RAM, which is known as Static RAM(SRAM). Unlike the Dynamic RAM, which we find inside the normal RAM, this static RAM is quite fast. And the typical size of this cache memory is in the range of KiloBytes up to the few MegaBytes. So, the data which is frequently required by the CPU can be supplied by this cache memory. Generally, some instructions and data which is required by the CPU are stored in this cache memory.

Now let's know the different types of the cache memory. There are three types of cache Memory,

Level 1 Cache Memory.

Level 2 Cache Memory.

Level 3 Cache Memory.

Level 1 Cache Memory:

The level 1 cache memory is a tiny amount of memory which is integrated inside the CPU itself. All the cores inside CPU have their individual level 1 cache memory. As this level 1 cache memory integrated inside the CPU, so they can operate at the same speed of the CPU. The Level 1 cache memory is fastest among all cache memories. Generally, this Level 1 cache memory is made by Registers.

The typical memory size of this level 1 cache memory is 2KB up to the 64 KB.

Level 2 Cache Memory:

The level 2 cache memory could be either inside the CPU or it could be outside the CPU. Most of the cases the level 2 cache memory are installed inside the CPU. This level 2 cache memory could be separate for all the cores or it could be shared between all cores of the CPU. If the level 2 cache memory is outside the CPU, then it is connected with a very high-speed bus with the CPU.

The memory size of this level 2 cache memory is in the range of 256 KB to the 512 KB.

Level 3 Cache Memory:

All the processors do not have this level 3 cache memory, some higher end processors have this level 3 cache memory. This level 3 cache memories are used to enhance the performance of the level 1 and level 2 cache memories. This level 3 cache memory is shared among all cores of the CPU and it is outside of the CPU.

The memory size of this level 3 cache memory is in the range of 1 MB up to the 8 MB.
