Abstract: With increasing various complexities of semiconductor devices due to growing performance, functionality requirements and with diminished time to market, the semiconductor firms try to develop null defect products in very less development time [1]. In SoC control unit plays a vital role and it is responsible for data transfers between blocks of the system, initialization and configuration, programming, power management etc. The processor present in the control unit executes the firmware from non-volatile memory (ROM). Replacement of the firmware might be required if there are defects in the preloaded code or if the additional feature is need to be implemented but replacing the firmware is very tedious and time consuming task and also it requires additional fabrication steps which could prove costly. Due this reason for the incorrect functions present in the firmware can be corrected with the expected functionality in Private Non Volatile Memory (PNVM) as a separate patch. This paper discusses the PNVM patch implementation
