If there are m input lines n output lines for a decoder that is used to uniquely address a byte addressable 1 KB RAM, then the minimum value of m+n is ________ .
Note – This question was Numerical Type.
(A) 18
(B) 1034
(C) 10
(D) 1024
Answer: (B)
Explanation: According to Decoder:
We need 210 outputs to map 1 KB RAM. For this we need 10 × 210 decoder.
Therefore,
Here m = 10 and n = 210
Hence,
m + n = 10 + 210 = 10 + 1024 = 1034
Option (B) is correct.
