What is high speed temp storage location that runs at the same speed as the central processing unit it is embedded within?

The high-speed temporary storage location that runs at the same speed as the central processing unit (CPU) it is embedded within is called the CPU cache. This cache is a small amount of very fast memory located on or very close to the CPU, allowing for quick access to frequently used data and instructions. It helps reduce latency and improve overall processing speed by minimizing the time the CPU spends waiting for data from slower main memory (RAM).
