B. Cache memory.

Explanation:

A cache memory, a special type of random access memory, is a memory that is easily accessibly by a system's CPU (or microprocessor) more quickly than even the regular random access memory. It serves as a buffer between the RAM and the processor. Frequently and commonly used data, programs and applications are temporarily stored in the cache memory so that they are readily accessible and available to the processor. It is as a matter of fact the fastest memory in a computer.

The cache memory comes in three levels - L1, L2 and L3.

L1 cache are often built into the computer's core (s). They are generally small in size between 8KB and 64KB.

L2 and L3 caches are larger than the L1 cache and most times are separate from the CPU.
