1. A method for operating bits of memory cells in a memory array, the method comprising:

  • applying operating pulses to at least one of Type-I bits and Type-II bits of a sample of memory cells, a Type-I bit being defined as a bit in a dual bit cell whose other bit is erased and a Type-II bit being defined as a bit in a dual bit cell whose other bit is programmed;

    determining a response of at least one of an electrical, physical and mechanical property of said at least one of Type-I bits and Type-II bits to said operating pulses;

    applying at least one operating pulse as a function of said response to at least some other Type-I bits of said array; and

    applying at least one further operating pulse as a function of said response to at least some other Type-II bits of said array.
