FIXED VALUE STORAGE CELL ARRANGEMENT AND METHOD OF PRODUCING THE SAME

摘要

The invention concerns a fixed value storage cell arrangement comprising, in a substrate (21) of semiconductor material, storage cells each having a vertical MOS transistor. The various logical values (zero, one) are brought about by gate dielectrics (27, 28) of different thicknesses. The storage cell arrangement can be produced in particular in a silicon substrate using few process steps and a high packing density. The storage cell arrangement and a readout control circuit can thus be produced integrally.
