81. Which of the following describes the action of storing a bit of data in a mask ROM?
  • A 1 is stored in a bipolar cell by opening the base connection to the address line.
  • A 0 is stored in a bipolar cell by shorting the base connection to the address line.
  • A 1 is stored by connecting the gate of a MOS cell to the address line.
  • A 0 is stored by connecting the gate of a MOS cell to the address line.
