Abstract
In a non-volatile memory cell having a floating gate (EEPROM), it is necessary to achieve a large coupling capacitance between the floating gate and a control gate in which the gates take up as little space as possible. To that end, it is provided that a dielectric between the floating gate and the control gate runs, in portions, approximately perpendicularly to the surface of a semiconductor substrate, for example, with the control gate configured within a U-shaped or pot-shaped floating gate.
