ABSTRACT:
A circuit for detecting the coincidence between a binary information unit stored therein and an external datum comprises at least one programmable memory element, a sensing circuit for reading a datum stored in the programmable memory element and a digital comparator for comparing the datum stored in the programmable memory element with the external datum. The sensing circuit comprises a bistable latch having at least one set input coupled to the programmable memory element and an output suitable to take either one of two logic levels according to a programming state of the programmable memory element, the output supplying directly the digital comparator.
