A non-volatile memory (NVM) circuit includes at least two types of NVM sub-circuits that share common support circuitry. Different types of NVM sub-circuits include ordinary NVM circuits that provide a logic output upon being addressed, programmable fuses that provide an output upon transitioning to a power-on state, NVM circuits that provide an ON/OFF state output, and the like. Some of the outputs are used to calibrate circuits within a device following power-on. Other outputs are used to store information to be employed by various circuits.
