1. A multiple-level memory cell, comprising:
- a storage element formed of several polysilicon resistors connected in series between two input/output terminals;
a load in series with said resistive element, the junction point thereof forming a read terminal of the memory cell, and the respective junctions between said resistors of the storage element being accessible; and
wherein at least certain points among said junctions of the storage element and the junction of this element with the load, are connectable, individually by a switch, either to one of said input/output terminals of the storage element, or to a terminal of application of a predetermined voltage, wherein individual programming of the resistors may be performed.
