Erasable programmable read-only memory
An Erasable programmable read-only memory (EPROM) is a computer memory chip which is normally read only, but can be erased and then re-programmed.
There are two main types:
- UV erasable, these have a window in the middle of the package. Shining ultraviolet light onto the window will erase the memory in, typically, 10 to 20 minutes.
- Electrically erasable, see EEPROM.
