ABSTRACT:
A circuit for the detection of current leaks on a bit line of a memory (such as an EPROM or flash EPROM), which includes a current generator and a means to apply zero volts to the gates of all the cells of the bit line. The detection information is delivered by a comparison circuit. It corresponds to the result of the comparison between the test current and the current flowing in the bit line. Advantageously, the detection circuit is incorporated into the read circuit of the memory. Also disclosed is the associated detection method and a memory circuit includes a detection circuit.
