What is cache memory?

Cache memory is a type of fast, relatively small memory that is stored on computer hardware.

Commonly shortened to cache, it is classed as random access memory which computer microprocessors can access more quickly than regular RAM.

Also frequently called CPU memory, it is typically directly integrated with the CPU chip, or is placed on a separate chip that can connect to the CPU via a separate bus interconnect.

The purpose of cache memory is to store program instructions that are frequently used by software during its general operations, this is why fast access is needed as it helps to keep the program running quickly.
