Q1:

How many 2K × 8 ROM chips would be required to build a 16K × 8 memory system?

A 2

B 4

C 8

D 16

ANS:C - 8

Since the required data bits are same so, we need only 8, 2k x 8 ROM chips. These chips will be connected in parallel and only one chip will be active at a time through address lines (14 lines). Extra three lines will be used to active one chip among 8 chips.
