Question

Which of the following statement is correct?

• A. Static RAMs are faster than dynamic RAMs
• B. RAMs cannot be used to realise read/write memory
• C. RAMs are not random access devices
• D. RAMs are generally non-volatile

Hint:

SRAM = Fast, costly, volatile. DRAM = Slower, needs refresh.

Answer 1

The Correct Option is A

When comparing different types of RAM, it's essential to understand the key differences between static RAM (SRAM) and dynamic RAM (DRAM). One of the main differentiators is speed. Static RAMs are indeed faster than dynamic RAMs. Here is a brief explanation:

• Static RAM (SRAM): SRAM uses multiple transistors for each memory cell and does not need to be periodically refreshed. This design allows for faster data access.
• Dynamic RAM (DRAM): DRAM uses a single transistor and a capacitor for each memory cell, requiring constant refreshing to maintain data. This refresh process leads to slower access times compared to SRAM.

Given these characteristics, the correct statement is: Static RAMs are faster than dynamic RAMs.
