IC integration levels An integrated circuit that contains approximately 12 to 100 equivalent logic gates on one chip is classified as which level of integration?
-
ASSI
-
BMSI
-
CLSI
-
DVLSI
Answer
Correct Answer: MSI
Explanation
Introduction / Context:IC classification by integration level is a historical but still useful way to compare circuit complexity and packaging constraints. These categories appear in datasheets and textbooks.
Given Data / Assumptions:
- Target complexity: roughly 12–100 equivalent gates.
- Standard categories: SSI, MSI, LSI, VLSI.
Concept / Approach:Small-Scale Integration (SSI) typically includes a handful of gates. Medium-Scale Integration (MSI) aggregates tens of gates (dozens). Large-Scale Integration (LSI) spans hundreds to thousands, and Very-Large-Scale Integration (VLSI) covers tens of thousands to billions in modern contexts.
Step-by-Step Solution:Match range 12–100 gates → squarely within MSI.SSI is too small; LSI/VLSI are much larger.Therefore, classification is MSI.
Verification / Alternative check:Classic TTL MSI families include counters, multiplexers, and adders—typically in the tens of gates range.
Why Other Options Are Wrong:SSI: generally 1–10 gates only.LSI and VLSI: exceed 100 gates by large margins.
Common Pitfalls:Assuming strict numeric boundaries; while approximate, 12–100 gates is conventionally MSI.
Final Answer:MSI
