Cache-only memory architecture

Imagine you have a toy box with all of your favorite toys. When you want to play with one of the toys, you have to search through the box to find it. This takes time and can sometimes be frustrating.

Now imagine your mom creates a special shelf just for your most favorite toys. These toys are easy to find and can be quickly accessed whenever you want to play with them. This is like a cache-only memory architecture.

In a computer, the main memory is like the toy box and the processor needs to access this memory to perform tasks. However, searching through the main memory for specific data can take a lot of time. To make the process quicker, a small and fast cache memory is included in the processor.

Cache-only memory architecture means that the processor no longer accesses the main memory at all, but relies solely on the cache memory for data. This can make the computer run much faster since the cache memory is much closer to the processor and can be accessed much more quickly than the main memory.

Overall, it's like having your most favorite toys right next to you so you can play with them whenever you want and not have to waste time looking through a big toy box.
