Circuit for controlling a flash EEPROM having three distinct modes of operation by allowing multiple functionality of a single pin

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