Which ROM type can be completely erased by exposing its internal semiconductor die to strong ultraviolet (UV) light waves? MCQ with Answer and Explanation
Which ROM type can be completely erased by exposing its internal semiconductor die to strong ultraviolet (UV) light waves?
A. PROM
B. EPROM
C. Flash ROM
D. EEPROM
Answer: Option B
Solution (By JKSSB Mock Tests)
EPROM (Erasable Programmable Read-Only Memory) chips feature a distinctive transparent quartz window over the die through which ultraviolet light is applied to erase data.
Explanation:
CD-ROM (Compact Disc Read-Only Memory) uses laser beams to read microscopic pits and lands on the surface of the disc, classifying it as optical storage.
Explanation:
3D NAND technology stacks flash memory cells vertically in multiple layers, allowing manufacturers to achieve massive storage densities on a single silicon die.
