What is cache memory?
What will be an ideal response?
Cache memory is derived from the French word for hidden and is a form of very fast memory that shadows
main memory. However, the size or capacity of the cache memory is only a fraction of the size of the main
memory (for example, 8 MB cache and 4 GB DRAM main store). Cache memory systems are designed so that
the most frequently used data is in the cache and, therefore, the average access time of the memory system is
much reduced.
