Abstract
In the method for testing a memory cell, a test voltage is applied to a memory cell and the test voltage is changed, preferably in incremental or decremental steps, during the testing. From the shape of the hysteresis of the memory cell it is determined whether or not the memory cell is a weak or substandard memory cell.
