EPROM
EPROM. or an Erasable PROM [Programmable Read Only Memory] is the same as an EEPROM except that an EPROM needs to be erased by Ultra-Violet [UV] light and not with an electric field. Because EPROMs require UV light to be erased they require a transparent window on the top of the device. Another type of EPROM that does not have a window; One Time Programmable EPROMs [OTP] are meant to be programmed only once so do not require a window to be erased. A PROM retains it stored memory even after power is removed.
EEPROM
EEPROM. or an Electrically Erasable PROM [Programmable Read Only Memory] is the same as an EPROM except that does not require UV light to be erased. So an EEPROM does not require a window. An EEPROM is erased by applying a voltage to one of the pins on the IC.
