Definition
The separation between a memory read signal representing stored states and the sensing or reference decision boundary used to distinguish those states.
Application
Used to assess memory sensing robustness across process, voltage, temperature, device variation, and scaling; inadequate read margin increases the risk of incorrect state detection.
