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.
