What is cache memory? Explain its functions

Cache memory is a high speed memory in the CPU that is used for faster access to data. It provides the processor with the most frequently requested data. Cache memory increases performance and allows faster retrieval of data.

What is cache memory? Explain its functions

Cache memory is RAM. The most recently processing data is stored in cache memory. CPU can access this data more quickly than it can access data in RAM. When the microprocessor starts processing the data, it first checks in cache memory.

The size of each cache block ranges from 1 to 16 bytes. Every location has an index that corresponds to the location which has data to access. This index is known as address. The locations have tags; each contains the index and the datum in the memory that is needed to be cached.

chache memory
it is placed in between the CPU and main memory . it is much faster than the main memory.

cache memory is the fastest memory that is placed between the c.p.u and the main memory.

Cache memory in not RAM, It is the memory associated with the CPU to reduce the memory access time.
