Abstract
A programming method of a multilevel memory cell is able to store a plurality of bits in a plurality of levels. The method includes writing a logic value in the multilevel memory cell by setting one of the programming levels thereof, these levels being included in the plurality of levels, with respect to a reference level according to the symbol to be written and to a previous programming level. The writing step is repeated until a highest possible value for the levels is reached. A multilevel memory device includes a plurality of multilevel memory cells organized into sectors, split into a plurality of data units whereon a programming operation is performed in parallel.
