Address and Data lines required to access 32 kB, byte organised memory will be :
Answer: D
The memory needs 15 address lines and 8 data lines.
A byte-organised memory stores one 8-bit byte at each address, so it needs 8 data lines. The number of address lines n must satisfy \(2^{n} = \) number of locations:
\[ \begin{aligned} 32\ \text{kB} &= 32 \times 1024 \\ &= 2^{5} \times 2^{10} = 2^{15} \end{aligned} \]
so 15 address lines are needed. 12 and 13 address lines would reach only 4 kB and 8 kB, and '32 and 1' confuses the capacity with the number of lines.
