Question

Assume a 24 but MAR that is organized as follows: row select lines 12 bits, column select lines 12 bits. What is the maximum size of the memory unit on this machine? What are the dimensions of the memory, assuming a square two dimensional organization? Assume a 24 but MAR that is organized as follows: row select lines 12 bits, column select lines 12 bits. What is the maximum size of the memory unit on this machine? What are the dimensions of the memory, assuming a square two dimensional organization?

Explanation / Answer

Solution:

Row select lines=12,

Column select lines=12,

MAR bits n=24 bits

Then

The maximum size of the memory unit on this machine: 2^n.

=> 2^24

=> 16 Mb

The dimensions of the two-dimensional memory: 2^row select lines × 2^column select lines

=> 2^12 x 2^12

=> 4096 × 4096.
