What are the two types of cache memory? A. Volatile and nonvolatile
B. DRAM and SRAM
C. Primary and secondary
D. Physical and virtual
The correct answer is B. DRAM and SRAM.
Explanation: Cache memory is primarily categorized into two types:
1. DRAM (Dynamic Random Access Memory): This type of cache stores each bit of data in a separate capacitor within an integrated circuit, which needs to be refreshed thousands of times per second. It’s typically slower than SRAM but can store more data in the same physical space.
2. SRAM (Static Random Access Memory): This type does not need to be refreshed like DRAM and is faster, making it suitable for use in cache memory. However, it is more expensive and consumes more power than DRAM.
Together, these two types of cache memory help improve the speed of data access for the processor.
