Scratchpad RAM

Scratchpad RAM (SRAM) is a type of computer memory that helps the processor of a device to work faster. Think of it like a desk or workspace for the processor.

Imagine you have a big project to finish, like building a puzzle. You start by opening the box and sorting out all the pieces. You will need a flat surface to put the pieces together or else it will be hard to remember which pieces go where. Scratchpad RAM serves as that flat surface or workspace for the processor to access data quickly.

When a device needs to access frequently used data or instructions, it can keep them in the scratchpad RAM. This makes it quicker to retrieve them and eliminates the need for the device to retrieve them from external memory or storage, which can be slower.

Think of it as a small notebook or scratch pad close to the computer processor. Instead of having to go to the book shelf or closet to look for a book you need, you can quickly write it down in your scratch pad and find it easily whenever you need it.

Overall, scratchpad RAM helps to improve the efficiency and performance of devices, such as gaming consoles, smartphones, and other smart devices, by reducing the time it takes for the processor to retrieve frequently used data.
