DEFINITION

Classification: 326/46

Sequential (i.e., finite state machine) or with flip-flop:

(under subclass 37) Subject matter comprising a logic circuit which has an output state dependent on a previous input state or which has two or more distinct current-conductive stable states and which toggles from one state to the other in response to an external stimulus.

(1) Note. A flip-flop is the most common memory element in a sequential circuit which requires a storage of previous input information.
