Abstract: The inventions relate to methods for trimming integrated circuits. Various embodiments include providing a method to trim an integrated circuit wherein trim data is stored in an on-board memory and then sent off of the circuit to be operated on by an external device. Corresponding trim data is then sent back to the integrated circuit in order to potentially modify the function of one or more analog devices along the circuit. Other embodiments include methods for trimming integrated circuits wherein trim data is stored in an on-board memory and retrieved using an on-board sequencer. The retrieved data is used to modify a function of one or more analog devices on the integrated circuit.
