The correct answer is USEPROM.PROM: A programmable read-only memory (PROM) is a form of digital memory where the contents can be changed once after manufacture of the device.The data is then permanent and cannot be changed. It is one type of read-only memory (ROM).EPROM: An EPROM, or erasable programmable read-only memory, is a type of programmable read-only memory chip that retains its data when its power supply is switched off.Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile. ?EEPROM: EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that allow users to erase and reprogram stored data repeatedly in an application.In contrast to EPROM chips, EEPROM memory does not need to be removed from the computer in order to modify the data.
