1.	Which of the following best describes EPROMs?(a) EPROMs can be programmed only once(b) EPROMs can be erased by UV(c) EPROMs can be erased by shorting all inputs to the ground(d) EPROMs can be erased electricallyThis question was posed to me at a job interview.Enquiry is from Read Only Memory (ROM) in section Memory Devices of Digital Circuits
Answer» The CORRECT answer is (b) EPROMs can be erased by UV The best I can EXPLAIN: EPROM (Erasable Programmable ROMs), the ROM is cleared by exposing it to UV RADIATION and also it’s a tedious PROCESS. Whereas, in EEPROM, the ROM can be cleared electrically and thus is less time consuming and more efficient.
