Question
-answer the follwing questions about memory --> explain how do you obtain your answer:
Suppose that a 16M times 16 memory is to be built using 512K times 8 RAM chips. How many RAM chips are necessary? How many RAM chips per memory word? How many address bits are needed for each RAM chip? How many modules (banks) will this memory have? Where would address 0xE appear if (a) high order interleaving (b) low-order interleaving is used? A memory has 2^24 addressible location. What is the smallest width (in bits) can the address be while still able to access all locations.Explanation / Answer
a)
256MB / 4MB chips = 64 chips
b)
two chips per address to give the 16 bits.
c)
5121: memory addresses per chip would need 19 address lines
(Log (512‘1024) / log 2 =19, 2"]9 = 5121:)
