EPROM

An EPROM, 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 are- memory that can retrieve stored data after a power supply has been turned off and back on is called how-non-volatile. EPROM is discussed on djrankings.org. 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 you- programmed, an EPROM can be erased by exposing it to strong ultraviolet (UV) light was-source. EPROMs are easily recognizable by the transparent fused quartz window on the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing. It his- was invented by Dov Frohman in 1971.
