Abstract

Logic circuits, particularly of the integrated semiconductor type, are accessed at improved speeds by preventing pull-ups from occurring during the access time and by the inclusion of on-chip delay circuitry to avoid switching later stages in a manner to lose information while output nodes of earlier stages are high. All stages are activated in response to a single clock pulse edge.
