De-glitch circuitry selectively responds to the time duration of actuation signals for selecting between pages in a read only memory. The de-glitch circuitry uses MOSFET transistors to act as resistors and capacitors in order to provide an RC time constant. The RC time constant is selected to allow the de-glitch circuitry to eliminate spurious glitches and prevent unwanted segment selections in the memory. The de-glitch circuitry is used with a voltage reference generator, segment selection decoders, sense amplifiers, and a flip-flop; all of which are constructed of MOSFET transistors and incorporated in a read only memory integrated circuit chip. The de-glitch circuitry is particularly useful in the construction of program cartridges for video game computer systems.
