Which feature of memory makes EPROM different from standard ROM?

EPROM, or Erasable Programmable Read-Only Memory, stands out from standard ROM due to its ability to be erased. The key characteristic of EPROM is that it allows for the removal of previously stored data through exposure to ultraviolet light, enabling the chip to be reused for different data storage needs. This is significant because, while standard ROM can only be programmed during manufacturing and cannot be altered afterward, EPROM provides the flexibility to update the information stored within it.

This capability is particularly valuable in applications where the data might need to be refreshed or changed, making EPROM suitable for development and testing phases of electronic designs, as well as in applications where software updates are necessary. Other options such as the ability to be written multiple times or being faster do not accurately represent the unique aspect of EPROM when compared to standard ROM.
