The correct answer is PROM.ROM is a non-volatile memory where the memory content could be read multiple times but could not be written.There are 4 types of ROM: MROM, PROM, EPROM, and EEPROM.Masked read-only memory (MROM): ?It is a type of ROM, that is masked off during production. It is used in systems that require long-term sustainability.Programmable read-only memory (PROM):?It is a memory that can be programmed only once after it is created. Once programmed, the information written is permanent and cannot be deleted. Erasable Programmable read-only memory (EPROM):It is a programmable ROM that can be erased and re-used. It can be erased by exposing it to ultra-violet light.Electrically Erasable and Programmable Read-Only Memory (EEPROM): It is a programmable ROM that allows the stored data to be erased electrically.
