Abstract: A reading method for a memory device with error-correcting encoding envisages the steps of: carrying out a first reading of a plurality of memory locations (A 0 , A 1 , ..., A LS-1 ) to generate a first recovered string (S 1 ), and performing a first decoding attempt using the first recovered string (S 1 ). When the first decoding attempt fails, the memory locations are read at least one second time, and at least one second recovered string (S 2 -S N ) is generated. On the basis of a comparison between the first recovered string (S 1 ) and the second recovered string (S 2 -S N ), a modified string (S M ) is generated, in which erasures (X) are located, and at least one second decoding attempt is carried out using the modified string (S M ).
