A method for wear reduction of a flash memory module, the method may include reading data stored in a group of flash memory cells to provide a read data; wherein the reading comprise supplying a bias voltage that is lower than a write bias voltage; wherein the write bias voltage was supplied to the group of flash memory cells during a writing of the data to the group of flash memory cells; and decoding the read data, by applying a decoding process of a given complexity, to provide decoded data.
