EPROM (erasable programmable read-only memory) is memory that does not lose its data when the power supply is cut off. The data can be erased and the chip reprogrammed by shining an intense ultraviolet (UV) light through a window designed into the memory chip.
An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile.
EPROM, form of computer memory that does not lose its content when the power supply is cut off and that can be erased and reused. EPROMs are generally employed for programs designed for repeated use but that can be upgraded with a later version of a program. EPROMs are erased with ultraviolet light.
EEPROM or E2PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.
18 Ιουλ 2024 · Short for Erasable Programmable Read-Only Memory, EPROM is a non-volatile memory chip that was invented by Dov Frohman in 1971 while at Intel that can only be read. If exposed to ultraviolet light, an EPROM can be reprogrammed if needed, but otherwise does not accept or save any new data.
24 Ιαν 2019 · Description. EPROM, unlike PROM and OTP can be erased. Early devices used strong ultraviolet light and would reset the entire chip back to its unprogrammed state. The UV light enables charge on a floating gate to be dissipated. The EPROM was invented by Dov Frohman of Intel in 1971.
28 Νοε 2022 · The EPROM, sometimes called EROM, is an abbreviation for erasable programmable read-only memory. It is a type of programmable read-only memory (PROM) chip that can retain its data when its power is turned off.
