An EPROM, or erasable programmable read-only memory, is a type of programmable read-only memory chip that retains its data when its power supply is switched off. Computer memory that can retrieve stor

…EEPROMs in some applications, but are expected to remain a small fraction of the EEPROM market for the foreseeable future. The difference between EPROM and EEPROM lies in the way that the memory programs and erases. EEPROM can be programmed and erased electrically using field electron emission (more…
An EPROM: the Texas Instruments TMS27C040, a CMOS chip with 4 megabits of storage and 8-bit output (shown here in a 600-mil ceramic dual-in-line package). The TMS27C040 operates at 5 volts, but must be programmed at 13 volts.
An Intel 1702A EPROM, one of the earliest EPROM types (1971), 256 by 8 bit. The small quartz window admits UV light for erasure.
