Most strategies for replacing magnetic core memory with semiconductor memory have experienced drawbacks. For example, a battery-backed complementary metal-oxide semiconductor (CMOS) static random-access memory (SRAM) approach has a limited temperature range, limited shelf life, and can present a potential chemical hazard depending on battery technology utilized. Correspondingly, the use of electrically erasable programmable read only memories (EEPROMs) alone imposes an unrealistic limitation on the number of write cycles. A strategy which has none of the above limitations and is simple and inexpensive to implement is described in the following.
