ANSWER ONLY D, E, & F
Suppose that a 2M x 16 main memory is built using 256K x 8
RAM chips and memory is
word-addressable.

b) If we were accessing one full word, how many chips would
be involved?
c) How many address bits are needed for each RAM chip?
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 14
(which is E in hex) be
located?
g) Repeat Exercise f) for low-order interleaving.
