Claim 20:
21. A method for operating a memory device comprising a memory cell and a plurality of evaluation elements, wherein each evaluation element of the plurality of evaluation elements is connectable with the memory cell of the memory device and is configured to evaluate a physical parameter, of the memory cell, comprising at least one of a voltage at the memory cell, a potential at the memory cell, a current through the memory cell or an electrical resistance of the memory cell, the method comprising:
connecting the memory cell to a first evaluation element but not a second evaluation element in a first state;
obtaining, based on one or more first evaluations of one or more physical parameters of the memory cell, a first evaluation result, of the memory cell, using the first evaluation element;
connecting the memory cell to the second evaluation element in a second state but not the first evaluation element;
obtaining, based on one or more second evaluations of one or more physical parameters of the memory cell, a second evaluation result, of the memory cell, using the second evaluation element;
determining a deviation between the first evaluation result and the second evaluation result to obtain a deviation information; and
storing the deviation information in a memory.
