Correct:
A
Explanation
Flash memory is a type of non-volatile memory, meaning it retains stored data even after the power is turned off. It is technically a specific type of EEPROM (Electrically Erasable Programmable Read-Only Memory) that can be erased and reprogrammed in large blocks.
- Option A: This describes EPROM (Erasable Programmable Read-Only Memory), which requires exposure to strong ultraviolet light through a transparent quartz window to erase data. Flash memory does not use UV light; it uses electrical signals.
- Option B: Correct characteristic; flash is a high-speed variation of EEPROM.
- Options C and D: Correct characteristics; being non-volatile, it inherently retains data without power.
Therefore, statement A is the only one that is not a characteristic of flash memory.
