Suppose that a 64MB system memory is built from 64 1MB RAM chips. How many address lines are needed to select one of the memory
alexdok [17]

Answer:

6 address lines

Explanation:

The computation of the number of address lines needed is shown below:

Given that

Total memory = 64MB

= 2^6MB

=2^{26} bytes

Also we know that in 1MB RAM the number of chips is 6

So, the number of address lines is 2^{26} address i..e 26 address lines

And, the size of one chip is equivalent to 1 MB i.e. 2^{20} bytes

For a single 1MB chips of RAM, the number of address lines is

\frac{2^{26}}{2^{20}} \\\\= 2^6 address

Therefore 6 address lines needed
