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.

memory access time.
The formula to calculate the average memory access time in a computer system is: Average Memory Access Time Hit Time Miss Rate x Miss Penalty
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.
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.
Drum.
cache memory refreshes instantly so access time is faster
