<p>A multi-page ROM uses programmable pointers (11) for selection ofa page. The pointers each have a preliminary latch circuit (36), an output latch circuit (38), and a delay circuit (32). The preliminary latch circuit (36) receives and stores program address signals when a first signal is present. The output latch (38) receives the address stored in the preliminary latch (36) when a secondsignal is present. The delay circuit (32) removes the first signal before the second signal is present and delays the presence of the first signal for a delay period following the removal of the second signal. </p> |
