Abstract

A memory cell, memory cell arrangement, and method for producing a memory cell arrangement is described where electric charge carriers can be introduced from a trench structure, which delivers charge carriers, into a charge storage area by applying a predefined electrical potential to the cell. The memory cell provides for programming with a reduced energy requirement
