Draw the logic diagram of 16-bit ROM Array and explain its principle of operation.
Ans:
16-bit ROM Array: A ROM that is read-only memory is an array of selectively closed and open unidirectional contacts. A 16-bit ROM array is demonstrated in Fig. (b). To choose any one of the 16 bits, a 4-bit address (A3, A2, A1, A0) is needed. The lower order two bits (A1, A0) are decoded through the decoder DL that selects one of the four rows, while the higher order two bits (A3, A2) are decoded through the decoder DH that activates one of the 4 column sense amplifiers.

The diode matrix is made by connecting one diode with a switch among each row and column. For illustration the diode D21 is connected in between column 1 and row 2. The output is enabled through applying logic 1 at the CS input that is chip select. Programming a ROM implies to selectively open and close the switches in series along with the diodes. For illustration, if the switch of diode D21 is into closed position and if the address input is 0110, the row 2 is activated linking this to the column 1. As well the sense amplifier of column 1 is enabled that provides logic 1 output if the chip is selected means CS = 1. It shows as a logic1 is stored at the address 0110. Conversely, if the switch of diode D21 is open, logic 0 is stored on the address 0110.
