    • Options
    • A. access time
    • B. data hold
    • C. read cycle time

    • 6. Advantage(s) of an EEPROM over an EPROM is/are:

    • Options
    • A. the EPROM can be erased with ultraviolet light in much less time than an EEPROM
    • B. the EEPROM can be erased and reprogrammed without removal from the circuit

    • 7. The condition occurring when two or more devices try to write data to a bus simultaneously is called ________.

    • Options
    • A. address decoding
    • B. bus contention
    • C. bus collisions

    • 8. Refer to the given figures (a) and (b). A logic analyzer is used to check the circuit in figure (a) and displays the waveforms shown in figure (b). The actual analyzer display shows all four data outputs, Q0-Q3. The analyzer's cursor is placed at position X and all four of the data output lines show a LOW level output. What is wrong, if anything, with the circuit?


    • Options
    • A. Nothing is wrong, according to the display. The outputs are in the open state and should show zero output voltage.
    • B. The circuit is in the READ mode and the outputs, Q0-Q3, should reflect the contents of the memory at that address. The chip is defective; replace the chip.
    • C. The circuit is in the mode and should be writing the contents of the selected address to Q0?Q3.
    • D. The Q0?Q3 lines can be either LOW or HIGH, since the chip is in the tristate mode in which case their level is unpredictable.
