Which memory type retains its contents without power and can be erased electrically in blocks?

  • A.mask ROM
  • B.ultraviolet erasable programmable ROM
  • C.flash
  • D.static random access memory

Answer: C

Block erasure is the distinguishing feature: byte-erasable non-volatile memory is EEPROM, and flash trades byte granularity for much higher density. It is why program memory is flash and small calibration stores are often EEPROM.
