An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile .
A cross section of legacy EPROM structure. Upper insulator: ONO Lower insulator: tunnel oxide STMicro M24C02 I²C serial type EEPROM Atmel AT93C46A die AT90USB162 MCU integrates 512 Byte EEPROM. EEPROM or E 2 PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory.
Floating-gate ROM semiconductor memory in the form of erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM) and flash memory can be erased and re-programmed. But usually, this can only be done at relatively slow speeds, may require special equipment to achieve, and is typically only ...
Other examples of non-volatile memory include read-only memory (ROM), EPROM (erasable programmable ROM) and EEPROM (electrically erasable programmable ROM), ferroelectric RAM, most types of computer data storage devices (e.g. disk storage, hard disk drives, optical discs, floppy disks, and magnetic tape), and early computer storage methods such ...
Another form of one-time programmable memory device uses the same semiconductor chip as an ultraviolet-erasable programmable read-only memory (UV-EPROM), but the finished device is put into an opaque package, instead of the expensive ceramic package with transparent quartz window required for erasing. These devices are programmed with the same ...
Sarah Strong scored 21 points and Azzi Fudd added 18 to help No. 2 UConn rout No. 22 Louisville 85-52 on Saturday night as part of the Women's Champions Classic. The Huskies (8-0) took control ...
The commission, Mexico's main anti-monopoly regulatory agency, is one of several independent agencies soon to be eliminated as part of what the government describes as a money-saving measure.
EPROM (Erasable programmable read-only memory or UVEPROM) – In this type the data in it can be rewritten by removing the chip from the circuit board, exposing it to an ultraviolet light to erase the existing data, and plugging it into a PROM programmer. The IC package has a small transparent "window" in the top to admit the UV light.
