Currently flash memory is widely used for data storage of mobile communication and automobile electronics. In this study the control program of multiple-execution has been designed to suppress the components and level of electromagnetic interference (EMI) noise generated during the data writing/reading of flash memory. The method designed by us can reduce the EMI noise levels of writing and reading operations by 4.39 dB and 2.91 dB respectively, while reducing the EMI noise components by 58.3% and 54.5% respectively, such that the noise interference by flash memory can be effectively reduced when it is used for various electronic devices. Especially for the automobile electronic systems, where the reduction of EMI noise interference can assure driving safety, and the reception sensitivity can be enhanced by suppressing the interference of RF module resulted from platform noise.
