Why do we need cache memory when we already have RAM (Random Access Memory), which is a kind of memory that is believed to be volatile? Random access memory, also known as cache memory, and RAM both employ the same kind of electrical components known as transistors. If it is even conceivable to do so, would it be possible to employ only one kind of memory to carry out all of a computer's functions?
