ABSTRACT:
A encoding method for a flash memory is provided, which can be used for reducing the memory wear and extend the endurance of the memory. The encoding method includes the steps as follows (A) receiving a set of information bits; (B) counting an amount of the information bits needed to be programmed in the set; (C) reversing the set of information bits if the amount of information bits needed to be programmed is less than half of the amount of whole information bits in the set, so that there are more than half of the information bits needed to be programmed in the reversed set; and (D) programming the information bits needed to be programmed in the reversing set, including the reverse flag bit for read out check.
