WRITING METHOD AND DEVICE DRIVER FOR FLASH MEMORY

A writing method and device driver for a flash memory is provided to improve a writing performance of a NAND flash memory by performing a selective writing order. A writing method and device driver for a flash memory comprises the following steps: a step for determining whether an inputted writing order is identical with a writing order stored in a driver or not(300); a step for covering the inputted writing order with the stored writing order if the inputted writing order is identical with the stored writing order(310); and a step for performing a writing by providing the stored writing order with a flash controller, if the inputted writing order is not identical with the stored writing order(320).
