It is a ROM with a special difference; its contents can be erased by ultraviolet light. An EPROM can thus be reprogrammed again and again, giving a single chip more lives than a cat, whereas the contents of an ordinary ROM are set for all time at the semiconductor factory and cannot be altered.
Can EPROM be reprogrammed?
EPROM(Erasable Programmable Read Only Memory) can be programmed and erased enabling them to be re-used. Erasure is accomplished using an UV (Ultra Violet) light source that shines through a quartz erasing window in the EPROM package.
Can EPROM chips be erased?
Unlike PROM (Programmable Read only Memory) It is possible to erase the data from a volatile EPROM by exposing it to a high-powered ultraviolet light source through a device known as an EPROM eraser. Programmers use an EPROM programmer to write data on the EPROM.
