ABSTRACT:
A circuit configuration and a method for automatic recognition and elimination of word line/bit line short circuits in a memory cell configuration containing sensor amplifiers, in which the sensor amplifiers split the memory cell configuration into memory blocks. To this end, a fuse is provided in the bit lines in each memory block upstream of the respective sensor amplifiers, the fuse being blown as a result of an appropriate voltage difference being applied in a test mode.
