memory cell size

1. What are the advantages and disadvantages of using a very large memory cell size, say, W = 64 instead of the standard size W = 8? If each integer occupies one 64-bit memory cell and is stored using sign/magnitude station, what are the largest (in terms of absolute value) positive and negative integers that can be stored? What if two cells are used to store integers?

2. At a minimum, how many bits are needed in the MAR with each of the following memory sizes?

a.

1 million bytes

b.

10 million bytes

c.

100 million bytes

d.

1 billion bytes

3. A memory unit that is said to be 640 KB would actually contain how many memory cells? What about a memory of 512 MB? What about a memory of 2 GB?
