EPROM

Erasable Programmable ROM

EPROM chips can be erased once programmed, thus making them ideal for testing new applications where a ROM chip will be required.

They can be easily recognised by the plastic 'window' on the top of the chip. This is used to erase the contents of the chip by shining ultra-violet light onto it.

EPROMs are expensive but reusable and are used for testing.
