In applications where the required memory capacity cannot be satisfied by a single available memory IC chip, what should the designer do to meet this requirement?
Ans:
If the particular memory chip cannot be give the essential memory capacity then the designer must do the given as:
(1) Determine the number of single chip required to full fill the total capacity through
Number of chip = Required capacity/Available capacity
(2) There are two kinds of expression
a. Raising memory location or words
b. Raising word size, that is number of bits in each word.
(3) In case a. the number will be have similar as the address lines of available chip. The dissimilarity of the address lines of the capacity 7 availability will provide the size of the decoder and the output of the decoder will decoded between the chips.
In case b. address line data lines will be common to each chip since all chips at similar location collectively generate a single word.
