A read-amplifier (PSA,NSA) for amplifying binary data signals is arranged between two mutually complementary bit-lines (BITLR,BITR) each connected to a storage column of the semiconductor store. A semiconductor switch (P3,N3) has its load output (P,N) connected to the read amplifier (PSA,NSA) and switches a supply potential (VDD,VSS) to the read-amplifier (PSA,NSA). A reference voltage source (VDD;VSS) provides a reference potential (VREF1,VREF2) switched to the load output (P,N) of the semiconductor switch (P3,N3), in which the absolute value of the reference potential (VREF1,VREF2) is less than or equal to the difference of the supply potential (VDD,VSS) and the working voltage of the semiconductor switch (P3,N4).
