Which type of memory is often faster but more expensive than traditional DRAM?

• A. SRAM
• B. Flash Memory
• C. EPROM
• D. DRAM

Answer: (A)

The correct choice is SRAM, which stands for Static Random Access Memory. It is faster than traditional DRAM, as it does not require periodic refreshing to maintain data, allowing for quicker access times. This characteristic makes SRAM suitable for applications where speed is critical, such as in cache memory for CPUs. In addition to its speed advantage, SRAM is also more expensive to manufacture than DRAM due to its more complex internal structure, which consists of multiple transistors per memory cell compared to DRAM's one transistor and one capacitor. This complexity contributes to higher costs but results in the improved performance needed in high-speed applications. The other options mentioned, such as Flash Memory, EPROM, and DRAM, serve different purposes or have distinct characteristics that do not align with the criteria of being faster yet more expensive than traditional DRAM. Flash Memory is non-volatile and commonly used for storage solutions, while EPROM is a type of read-only memory whose data can be electrically erased and reprogrammed. DRAM, while common and cost-effective for main system memory, is slower than SRAM. These distinctions highlight why SRAM is indeed the preferred answer.
