What component inside the CPU acts like ram?

The component inside the CPU that acts like RAM is the cache memory. Cache is a small, high-speed storage area located within or very close to the CPU, designed to temporarily hold frequently accessed data and instructions. It allows for faster data retrieval compared to accessing the main RAM, thereby improving overall processing speed and efficiency. Cache memory typically comes in multiple levels (L1, L2, and L3) with varying sizes and speeds.
