    Digital Electronics Memory and Storage: For the given circuit, which of the following is correct?


  • Options
  • A. The number 5 is being written to the memory at address location 203.
  • B. The chip has not been enabled, since the EN terminal is 0; therefore, nothing will be written to the chip and the output is tri-stated.
