The invention relates to a method and a
system for effectively prolonging the service life of NAND startup. The method comprises the steps that S1, starting a
chip, and completing initialization; s2,reading address information of the
firmware from the NAND particle fixed address X0; s3, judging whether reading is successful or not; if yes, entering S5; if not, entering S4; s4, selecting the nextfixed address Xn of the fixed address X0 for reading, and returning to the step S3; s5, reading the bootstrap program from the read address, and verifying the bootstrap program; s6, judging whether the
verification is successful or not; if yes, entering S7; if not, returning to S4; s7, running
firmware. Through two-stage mapping, the read fixed address is subjected to multiple backups, and
firmware is separated from the storage address, so that repeated erasing and writing of the same address by NAND particles are reduced, the service life of
chip NAND starting is prolonged, and the
service time of the
solid state disk is prolonged.
