D
Cache’s
Explanation: 

Detailed explanation-1: -Caches are widely used to speed up reads and writes in memory systems. Many microprocessor architectures include caches as part of their definition. The cache speeds up average memory access time when properly used.

Detailed explanation-2: -To reduce the memory access time we generally make use of a)Heapsb)Higher capacity RAM’sc)SDRAM’sd)Cache’sCorrect answer is option ‘D’.

Detailed explanation-3: -Cache memory is used to reduce the average memory access times. This is done by storing the data that is frequently accessed in main memory addresses, therefore, allowing the CPU to access the data faster.

Detailed explanation-4: -Cache Memory It is used to reduce the average time to access data from the Main memory.
