How many stable states does a flip-flop circuit have?

A flip-flop circuit has two stable states, which allows it to function as a basic memory component in digital electronics. Each stable state represents a particular binary value; these states are typically denoted as '0' and '1'. When the circuit is in one of these states, it retains the value until it is changed by an input signal.

The ability of a flip-flop to maintain its state in the absence of a clock signal or any other input is crucial for its role in storing binary information. This characteristic is fundamentally what distinguishes flip-flops from other types of circuits that may not have stable storage capabilities.
