Question 26
|
The capacity of a memory unit is defined by the number of words multiplied by the number of bits/word. How many separate address and data lines are needed for a memory of 4K × 16?
|
10 address, 16 data lines
|
|
|
11 address, 8 data lines
|
|
|
12 address, 16 data lines
|
|
|
12 address, 12 data lines
|
Question 26 Explanation:
ROM memory size = 2m × n
m = no. of address lines
n = no. of data lines
Given, 4K × 16 = 212 × 16
Address lines = 12
Data lines = 16
m = no. of address lines
n = no. of data lines
Given, 4K × 16 = 212 × 16
Address lines = 12
Data lines = 16
Correct Answer: C
