Abstract

A system-on-chip is provided that includes functional circuitry that performs a function. Control circuitry controls the function based one or more configuration parameters. Non-volatile storage circuitry includes a plurality of non-volatile storage cells each being adapted to write at least a bit of the one or more configuration parameters in a rewritable, persistent manner a plurality of times. Read circuitry locally accesses the non-volatile storage circuitry, obtains the one or more configuration parameters from the non-volatile storage circuitry and provides the one or more configuration parameters to the control circuitry. Write circuitry obtains the one or more configuration parameters and provides the one or more configuration parameters to the non-volatile storage circuitry by locally accessing the non-volatile storage circuitry.
