Data storage management method for OTP flash memory under embedded environment

The invention discloses a data storage management method for an OTP flash memory under an embedded environment, which comprises the following steps of: performing classification management on a file system area and a user data area, and performing different data storage management methods on the two areas so as to realize effective management of the OTP flash memory. In common data storage, address mapping can be implemented by simple calculation and combination of a bad block table and a page replacing table so as to simplify the management algorithm complexity; and the consumption of system resources is reduced by adopting a forward programming method in a file system.
