Method and device for generating dynamic partition information in Nand flash memory

The embodiment of the invention provides a method and device for generating dynamic partition information in a Nand flash memory. The method comprises the following steps of: analyzing original partition information which comprises n named partitions and the number of original blocks of each partition, wherein n is a positive integer; according to the number of the original blocks of the n partitions and the original start address of the first partition of the n partitions, detecting the state of each block of each partition in sequence, and generating the dynamic partition information of the n partitions, wherein the dynamic partition information comprises the dynamic start addresses and the number of the dynamic blocks of the n partitions; and storing the dynamic partition information in a specified area. The invention also provides the device corresponding to the method. According to the technical scheme provided by the invention, the method and the device can solve the problem of resource waste caused by
