What is the primary function of the Cache memory located between the central processing unit and main system RAM?
Answer and explanation
Correct answer: D. To store frequently accessed instructions and data to minimize memory latency
- Step 1: Accessing DRAM main memory requires dozens to hundreds of CPU clock cycles. Step 2. SRAM cache chips store recently and frequently requested data, allowing the processor to fetch instructions without stalling. Answer: To store frequently accessed instructions and data to minimize memory latency. Why not the others: Cache is volatile and does not provide permanent backup; peripheral I/O is handled by chipsets; power conversion is performed by power supply units.
