An EEPROM receives a first address from a microprocessor. If the first address equals a first predetermined value, the EEPROM goes into a programming mode. If the first address equals a second predetermined value, the EEPROM goes into an erase mode. The EEPROM interprets a second address received from the microprocessor as indicating the location where data is to be stored in the EEPROM. The EEPROM generates an internal write pulse which remains active until the EEPROM receives a subsequent write instruction from the microprocessor. In this way, it is not necessary to generate a wait instruction to the microprocessor to halt the microprocessor while the EEPROM is storing data. Also, it is not necessary to provide additional circuitry to control whether the EEPROM goes into the erase or programming modes.
