Exiting. --- Flip-Flop Types and Switching Physics --- SR Flip-Flop: Set-Reset, basic memory, built from NAND/NOR gates. D Flip-Flop: Data/Delay, synchronizes input to clock, used in registers. JK Flip-Flop: Universal, toggles or sets/resets based on inputs. T Flip-Flop: Toggle, divides clock, used in counters. All flip-flops are built from logic gates, so their switching speed is limited by the gate delay (set by electron drift and channel length). Estimated flip-flop delay: 1.02e-15 s (for 4 gates) Max flip-flop switching frequency: 9.80e+14 Hz
