- Fastest memory is cache memory.
- Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.
Which type of memory is fastest?
Registers are the fastest type of memory, which are located internal to a processor.
Which is the fastest memory RAM or cache?
Performance. CPU cache is built into the CPU or on an adjacent chip. Its memory access time reportedly is 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to the CPU request. RAM data access is faster than read-only memory and mechanical storage devices, such as hard disks and tape.
