An RFID tag includes a non-volatile memory (NVM) circuit with at least two
distinct 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.
