Question

An integrated circuit RAM chip has a capacity of 512 words of 8 bits each where the words are organized using a one-dimensional layout.a) How many address lines are there on the chip?b) How many such chips would be needed to construct a 4Kx16 memory?c) How many address and data lines needed for a 4Kx16 memory?#addresss lines = #data lines =

Answer 1

Answer:

A. 9

B. 16

C. Number of addresses = 12 number of data lines = 16

Explanation:

The capacity of this chip is 512 x 8

That is 512 words and these words have 8 bits

A. The number of the address lines would be

log2(512) = 2⁹

So the answer is 9

B. The total number of chips required

= 512 x 8 = 4096

(4096 x 2)/ 512 = 16

C. Number of address = log4092 = 2¹²

= 12

The number of data lines = 8x2 = 16

Thank you!
