EPROM stands for Erasable Programmable Read-Only Memory. EPROM is an early form of flash memory chip that retains its data after the power supply has been terminated. The most common use for this type of memory chip is for storing computer BIOS (Basic Input Output System) that is used to bootstrap a computer's operating system. Another common use of this type of memory chip is in the development of video game cartridges. EPROMs contain a quartz window that allows for the erasure of the stored data.
