This paper presents the development of a ROM writer for shmoo test of a flash memory integrated into the MCU(Micro Controller Unit). A shmoo test is a graphical display of the response of a component or system varying over a range of conditions and inputs. Often used to represent the results of the testing of complex electronic systems such as computers or integrated circuits such as DRAMs, ASICs or microprocessors. A shmoo test and data write time(32k) of the development ROM writer is 6.4 seconds, which was improved by about 20% compared to the rate of the currently used ROM writer.
