# computer has 24-bit address lines .What is maximum amount of memory

Suppose your computer has a processor with 24-bit address lines. What is maximum amount of memory that can be attached in your system? (Show the step(s) for calculation of maximum addressable memory)
Is This A Good Question/Topic? 0

By "attached" do you mean "addressed" by the system?

Also, please be aware that if there isn't a good faith effort, your thread will go to a magical place where it never rains.

So, what's the max value of a 24bit integer?

Don't know how you'd "show the steps". Perhaps you could just keep doubling.
e.g.
```Bit       Size
1           2
2           4
3           8
4          16

```

Well if this is a serial type processor then EACH address line has packets of 24bits so, the more address lines that you have then the more ram you can have......

or:

serial data specification example:

Quote

handshake (4bits)
data of packet (24bits)
parity (8bits)

wait for next packet

well the maximum addressable memory is 2^24 numbered from 0 to 2^24-1, since you have 24 address lines each one capable of carrying 1 bit.
