Explanation by: Mr. Dubey

the cross-coupled connections from the output of one gate to the input of the other gate constitute a feedback path. for this reason, the circuits of nor based s-r latch classified as asynchronous sequential circuits. moreover, they are referred to as asynchronous because they function in the absence of a clock pulse.
