18.45 Consider the use of the tree column decoder shown in Fig. 18.37 for application with a square 1-Mbit array. How many address bits are involved? How many levels of pass gates are used? How many pass transistors are there ...

18.44 For the column decoder shown in Fig. 18.37, how many column-address bits are needed in a 1-Mbit-square array? How many NMOS pass transistors are needed in the multiplexer? How many NMOS transistors are needed in the NOR decoder? How ...

18.43 Consider a 1024-row NOR decoder. To how many address bits does this correspond? How many output lines does the decoder have? How many input lines does the NOR array require? How many NMOS and PMOS transistors does such a ...

18.42 (a) For the sense amplifier of Fig. 18.34, show that the time required for the bit lines to reach 0.9VDD and 0.1VDD is given by td = (CB/Gm)ln(0.8VDD/ΔV), where ΔV is the initial difference voltage between the two bit ...
