Abstract
A cell arrangement comprising a memory cell arranged in parallel to a first capacitor is charged to a first voltage potential. A second capacitor is charged to a second voltage potential, which is higher than the first voltage potential. The second capacitor is connected to the cell arrangement while the voltage over the cell arrangement comprising the first capacitor is kept constant. The resulting current from the second capacitor through the memory cell is used to detect the state of the memory cell.
