Beginner Topic 13 of 51 Computer Architecture & Logic
Flip-Flops
One-bit memory elements that store state on a clock edge.
How it works
A flip-flop stores one bit and updates only on a clock edge. D flip-flops copy input D at the edge; JK and T variants toggle or set. Built from latches.
Where it is used
Registers, counters, state storage.
Common pitfall
Violating setup and hold times causes metastability.
Where it fits in the course
Flip-Flops is topic 13 of 51 in Computer Architecture & Logic, rated Beginner. It follows Multiplexers. The next topic is Registers.
Practice and explore
- Open the interactive lesson, with a mini quiz.
