Parameter Setting
What is parameter setting?
After wafer fabrication, all key application parameter of the device are stored in NVM for system function configuration and calibration.
During and after system assembly, certain parameters of the ICs may have to be configured and stored so that they can work efficiently with other system components. By adjusting the parameters, designers can calibrate performance discrepancies to match system specifications.
Driver ICs typically require NVM to store device parameters. For example, gray levels and gamma curves are stored in display driver ICs for image quality optimization. More complex systems may require real-time recording of system parameters (i.e. battery impedance) in order to improve product life (i.e. laptop battery packs).
