Which one of the following is UV erasable?

The correct answer is C. EPROM.

• Flash memory is a type of non-volatile memory that can be erased and reprogrammed in blocks. It is used in a variety of devices, including USB drives, digital cameras, and MP3 players.
• SRAM (Static Random-Access Memory) is a type of volatile memory that requires constant power to maintain its contents. It is used in high-speed applications, such as cache memory and registers.
• EPROM (Erasable Programmable Read-Only Memory) is a type of non-volatile memory that can be erased using ultraviolet light and programmed using an electronic device. It is used in applications where data needs to be stored for a long period of time, such as BIOS chips.
• DRAM (Dynamic Random-Access Memory) is a type of volatile memory that requires periodic refreshing to maintain its contents. It is used in applications where high-speed access to data is required, such as main memory in computers.

EPROM is the only type of memory listed that is UV erasable.
