metastability

This term describes a state of deceptive stability. It is used primarily in technical fields like physics, chemistry, and digital electronics to describe a system that remains in a specific state only because it lacks the energy or trigger to move toward a lower-energy, more stable equilibrium. It implies a fragility where a minor external shock can cause a sudden, irreversible transition.

In the context of digital electronics, the term carries a negative connotation of failure or unpredictability. It refers to a critical timing error where a flip-flop or latch enters an indeterminate state, potentially causing system crashes or data corruption. Because it is a technical property of a system's state, it is treated as an uncountable noun and does not have a plural form.
