Configuration PROMs (Programmable Read-Only Memory) are companion devices to FPGAs, used to store a user's desired configuration for the latter during periods when the device is powered down. The specific memory technology used varies and includes types which can be electrically erased and re-written, rendering their characterization as "read-only" devices somewhat anachronistic.
