Wikipedia
erasable programmable read-only memory
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. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source (such as from a mercury-vapor lamp). EPROMs are easily recognizable by the transparent fused quartz (or on later models resin) window on the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing.

erasable programmable read-only memory
Erasable Programmable Read-Only Memory (EPROM) is a type of memory chip that retains its data when its power supply is switched off and that can be reprogrammed by applying a voltage to erase data. It was extensively used in computers, microcontrollers, and other electronic devices to store firmware or software that needs infrequent updates, while retaining the ability to erase and rewrite the content better than ordinary PROM. However, the erasure is usually achieved using ultraviolet light, and not electrically. The data lasts many years but can be reprogrammed if needed.
