Which one of the following is not a characteristic of flash memory?
A.It is an ultraviolet erasable programmable ROM.✓ Correct
B.It is an electrically erasable programmable ROM.
C.It retains data without power.
D.It is a non-volatile memory.
Explanation
Flash memory is electrically erasable and programmable (a form of EEPROM), NOT ultraviolet erasable — UV-erasable memory refers to the older EPROM technology, which is different from flash. Flash memory is non-volatile, meaning it retains data without an external power supply, making it ideal for USB drives, SSDs, and memory cards. Hence option (a) is not a characteristic of flash memory.
