Question

The SRAM from a memory-read perspective, is indeed a combinational circuit because

• A. Its next state depends on its present state
• B. A data retrieval is not affected by previous data retrievals
• C. It is storage element
• D. It operates in sequential fashion

Hint:

Memory devices store data sequentially, but a read operation itself behaves as a combinational process.

Answer 1

The Correct Option is B

Concept: A combinational circuit produces outputs that depend only on present inputs. A sequential circuit depends on present inputs as well as previous states.

Step 1: Understand SRAM read operation.
During a memory read operation, the output data depends only on the address supplied.

Step 2: Check dependence on previous reads.
The current read operation is independent of any previous read operations. Hence SRAM behaves like a combinational circuit during reading.

Step 3: Select the correct option.
\[ \boxed{\text{A data retrieval is not affected by previous data retrievals}} \]
