单词 flash memory
释义
flash memory

Physics
  • A form of semiconductor storage in which the data may be altered electrically. The device does not need refreshing to maintain the data, which is stored even when power is removed. Flash memory finds application in computers, in digital cameras, and in portable storage devices that emulate hard disks (e.g. USB drives).


Computer
  • A form of storage evolved from EEPROM technology wherein the data may be altered electrically. The device does not need refreshing to maintain the data, which is stored even when power is removed. Flash memory finds application in computers for storing BIOS information, in digital cameras, and in portable storage devices that emulate hard disks (e.g. USB drives).


Electronics and Electrical Engineering
  • A type of electrical-erasable programmable ROM (EEPROM) that operates faster than traditional EEPROM and requires no power to hold its contents. Faster operation is achieved by erasing either a single block or the whole chip in one operation than by the traditional approach of erasing one byte at a time. Flash memory is commonly found in applications in which fast information storage is required, such as digital cameras, game consoles, and solid-state hard drives. See also USB flash drive.
