Which memory is fastest and located inside the CPU?
Registers
Registers are small storage locations built directly into the CPU itself, used to hold data, instructions, and addresses that are being processed immediately.
Because registers sit inside the processor and are accessed directly by the arithmetic and control units, they offer the fastest possible access speed in the memory hierarchy.
In contrast, Cache L3, RAM, and the hard disk are all located outside the CPU core and involve progressively slower access times.
Hence, registers are the fastest memory and are located inside the CPU.
