Abstract: With the Tibetan-Chinese-English electronic dictionary entry’s increase, and the application of audio and image, an energy saving, fast and large capacity storage system is needed in order to move the computer’s electronic dictionary to embedded systems. The large capacity NAND Flash chips interfaced with ARM is designed. The system is able to work stably, and the read and program operation can meet the requirements of the Tibetan-Chinese- English electronic dictionary.
