E 2 P R O M or EEPROM is used for the long term storage o f data such as the system configuration o f a circuit or for logging events o f a monitoring system. E 2 PROM does not require U V light to erase it, instead it can be erased electrically. This memory is not used as R A M as wri t ing the data is very slow. I t is used where long-term storage o f data is needed and a fast write time is not a major concern, e. g., the BIOS setup in an I B M compatible PC.
