COA: Primary Memory – Architecture of ROM (Part 3)
Topics discussed:
1) Revisiting the construction of 7 to 128 Decoder using 3 to 8 Decoders (example for understanding the generalized formula in the previous lecture).
2) Understanding the drawback of the old method.
3) Remodification of the construction of 7 to 128 Decoder using eighteen 3 to 8 Decoders and one 1 to 2 Decoder (at level 1).
4) Expansion of Decoder:
a) Construction of 4 to 16 Decoder using two 3 to 8 Decoders and a NOT gate.
b) Construction of 4 to 16 Decoder using two 3 to 8 Decoders and a 1 to 2 Decoder.
c) Construction of 5 to 32 Decoder using four 3 to 8 Decoders and a 2 to 4 Decoder.
