Erasable Programmable Read-Only Memory

   Also found in: Dictionary/thesaurus, Acronyms, Wikipedia, Hutchinson 0.07 sec.
(storage)Erasable Programmable Read-Only Memory - (EPROM) A type of storage device in which the data is determined by electrical charge stored in an isolated ("floating") MOS transistor gate. The isolation is good enough to retain the charge almost indefinitely (more than ten years) without an external power supply. The EPROM is programmed by "injecting" charge into the floating gate, using a technique based on the tunnel effect. This requires higher voltage than in normal operation (usually 12V - 25V). The floating gate can be discharged by applying ultraviolet light to the chip's surface through a quartz window in the package, erasing the memory contents and allowing the chip to be reprogrammed.

If a HMMWV with a newly installed transmission goes into "limp mode" (won't shift out of second gear right away, it could have the wrong erasable programmable read-only memory (EPROM) chip installed.
In addition, FRAM's fast write capability and unlimited write endurance make it superior to other types of nonvolatile memory, such as electrically erasable programmable read-only memory (EEPROM) or Flash.
