| Abstract: | In consideration of the memorizer which uses the flash memory as storage media, this paper proposes a RS algorithm to adapt to different resolutions, and a package of comprehensive approach is designed which has the full ability of recording storage and reading of the system. It solves the problem of lacking the reliable when the data in flash memory is rotating, and improve the quality of the system. Each process can remedy 3 Byte random errors, under the condition of 640×480 pixel, the maximum by page of correcting errors is up to 72 Byte, signal-to-noise ratio increases by more than 2 dB. |
