Bistability is widely used in digital electronics devices to store binary data. It is the essential characteristic of the flip-flop, a circuit widely used in latches and some types of semiconductor memory. A bistable device can store one bit of binary data, with one state representing a 0 and the other state a 1.n the mathematical language of dynamic systems analysis, one of the simplest bistable systems is. This system describes a ball rolling down a curve with shape, and has three steady-states: , , and. The middle steady-state is unstable, while the other two states are stable.
