Difficulty: Easy
Correct Answer: flip-flop memory circuitry
Explanation:
Introduction / Context:
Digital logic is divided into combinational and sequential categories. Sequential logic stores state and reacts to both current inputs and past history. Understanding alternative phrasing helps connect textbook terminology with practical design discussions.
Given Data / Assumptions:
Concept / Approach:
Because sequential circuits require flip-flops or latches to store state, they are often colloquially summarized as “flip-flop based memory circuitry.” This conveys the essential property: the presence of state (memory) updated by timing events.
Step-by-Step Solution:
Identify key trait of sequential logic: dependence on stored state.Recognize implementation: flip-flops/latches form the memory core.Map phrasing: “flip-flop memory circuitry” best matches sequential logic.Exclude unrelated terms: inverter (purely combinational), generic block names.
Verification / Alternative check:
State machines (Mealy/Moore) and pipelines are built from flip-flops plus combinational logic; documentation frequently refers to “sequential (flip-flop) logic.”
Why Other Options Are Wrong:
Common Pitfalls:
Confusing storage with just propagation delay; memory requires explicit state elements (flip-flops/latches), not gate delay.
Final Answer:
flip-flop memory circuitry
