Read only memory (ROM) code description
The category “Read Only Memory (ROM)” refers to a type of computer memory that stores data permanently and cannot be modified or erased by normal computer operations. It includes subcategories such as Programmable Read Only Memory (PROM), Erasable Programmable Read Only Memory (EPROM), and Electronically Erasable Programmable Read Only Memory (EEPROM). PROM is a type of ROM that can be programmed once with data that remains fixed. EPROM is a type of ROM that can be erased and reprogrammed using ultraviolet light. EEPROM is a type of ROM that can be electronically erased and reprogrammed multiple times. These subcategories are used to classify and categorize public procurement notices in the European Union related to the procurement of ROM-based products or services.
