Abstract
Electrical fuses/antifuses in a semiconductor memory configuration, such as in particular a DRAM, are read, instead of with the previously conventional internal voltage, with the voltage that defines the high potential of the bit lines of a memory cell array in the semiconductor memory. The high potential of the bit lines is defined by a voltage that is reduced relative to the internal voltage of the semiconductor memory.
