The main read only memory devices are listed below: ROM (Mask Programmable ROM —also called “MROMs”) EPROM (UV Erasable and Electrically Programmable ROM) OTP (One Time Programmable EPROM) EEPROM (Electrically Erasable and Programmable ROM) Flash Memory - These devices are covered in Section 10. EPROM (UV Erasable Programmable Read Only Memory) is a special type of ROM that is pro- grammed electrically and yet is erasable under UV light. The EPROM device is programmed by forcing an electrical charge on a small piece of polysilicon material (called the floating gate) located in the memory cell.
