1.	Which ROM can be erased by an electrical signal?(a) ROM(b) Mask ROM(c) EPROM(d) EEPROMI had been asked this question in class test.I'm obligated to ask this question of Read Only Memory (ROM) in chapter Memory Devices of Digital Circuits
Answer» Correct answer is (d) EEPROM Best explanation: In 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.
