The processor registers! Relatively, they are very small (a register on an Intel 32-bit processor is only 4 bytes large!) but they are very fast. Programs use them to store the part of data they are working on and some memory addresses.
Cache memory
Cache Memory.

cache memory
Usually the register set memory. The L1 cache may be as fast.
The time required by a processor to access data or to write data from and to memory chip is referred as access time.
The time required by a processor to access data or to write data from and to memory chip is referred as access time.
memory access time.
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
it is defined by access time and cycle time
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
Faster access time, greater cost per bit; greater capacity, smaller cost per bit; greater capacity, slower access time. As a general rule (but there are exceptions) the greater the capacity of a memory the longer the access time. For a higher cost the access time of a given capacity memory can usually be shortened some. As a general rule (but there are exceptions) the greater the capacity of a memory the total memory cost increases, but the memory cost per bit decreases.

cache memory refreshes instantly so access time is faster
Access time in case of computer memory is the time a program or device takes to locate single piece of information and then make it available to computer for processing.
