Abstract
A test structure for determining the electrical properties of a memory cell in a matrix-like cell array constructed on the basis of the single-sided buried strap concept has a connection between internal electrodes in the storage capacitors in two adjacent memory cells in the direction of the row of active regions in order to produce a series circuit. A first selection transistor and a first storage capacitor in a first memory cell and a second selection transistor and a second storage capacitor in a second memory cell, the active regions of the first and second selection transistors not being connected between the first and second selection transistors via a contact-making bit line.
