A multi-page ROM uses programmable pointers for selection of a page. The pointers each have a preliminary latch circuit, an output latch circuit, and a delay circuit. The preliminary latch circuit receives and stores program address signals when a first signal is present. The output latch receives the address stored in the preliminary latch when a second signal is present. The delay circuit 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.
