An integrated semiconductor memory includes a memory cell array with at
least one memory cell, in which a data value is stored, and an evaluation
circuit with a counter. During a test of the integrated semiconductor
memory, a counter reading of the counter is altered if the data value
stored in the memory cell deviates from a desired value. A threshold
value is predefined by a control circuit. A programming circuit compares
the threshold value on the input side with the instantaneous counter
reading of the counter. If the counter reading of the counter exceeds the
threshold value, a programming element changes from a first programming
state to a second programming state. After the conclusion of the test,
the state of the programming element is read out via an output terminal.
This scheme makes it possible to deduce a possible cause of failure of
the integrated semiconductor memory.
