3. Suppose that a 32M x 16 main memory is built using 512K × 8 RAM chips and memory is word-addressable.
A)
Total number of RAM chip required
= 32Mx16/512Kx8
= 64x2
= 128
B)
Main memory word size is 16 bit and our RAM chip word size is 8 bit.
So to read one full word, we need total of 2 chip.
C)
Total number of address bits for each chip
= Log(512K)
= 19 bits.
d) How many banks will this memory have?
e) How many address bits are needed for all of memory?
f) If high-order interleaving is used, where would address 32(base 10) be located? (Your answer should be "Bank#, Offset#")
g) Repeat (f) for low-order interleaving.
