ABSTRACT:
A semiconductor memory device, including a plurality of programmable memory cells each one adapted to be brought into one among at least a first status and a second status, said plurality of memory cells including memory cells intended to store data, and means for accessing the memory cells for reading/modifying their status. At least one memory cell in said plurality is used as detector memory cell, and control means operatively associated with the at least one detector memory cell are provided, said control means being adapted to establishing a potential loss of the data stored in the memory cells of said plurality based on a detected first status of the at least one detector memory cell.
