Abstract: A monolithic latent image memory is one having a plurality of bistable memory cells. Selected bistable memory cells include AC impedance means which are responsive at the transition from nonsustaining voltage level to an operating level so as to set the selected memory cells to a first predetermined state and thus provide a monolithic memory which is capable of functioning in a read-only and a read-write mode. The read-only state is selectively alterable by employing an AC impedance means which is multi-valued.
