It composed 16K × 16 memory by using two DRAM chips that have 8K
capacity. If the row × column matrix is square for the address, how
many address lines and how many data lines should each chip
have?
11. Suppose that a 32M × 16 memory built using 512K × 8 RAM
chips and memory is word-addressable.
a) How many RAM chips are necessary?
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...

Draw the diagram of a typical 16 Mb DRAM (4M X 4) and explain
its action. Draw the diagram of an SRAM cell and explain its
action.
Problem 9-16
One unit of A is composed of two units of B and three units of
C. Each B is composed of one unit of F. C is made of one unit of D,
one unit of E, and two units of F. Items A, B, C, and D have 15,
50, 45, and 25 units of on-hand inventory, respectively. Items A,
B, and C use lot-for-lot (L4L) as their lot-sizing technique, while
D, E, and F require multiples...
Describe what psychologists mean when they say that attention
and working memory have a limited capacity. Discuss at least two
implications of this limited capacity for learning in the
classroom.
A soybean farmer is hedging production using a fence composed of
the two following options positions on Nov 18 soybean futures:
Holding a put with a $10.00 strike price and a premium of $0.39
Writing a call with a $11.20 strike price and a premium of $0.29
(Note: Assume an expected basis of -$0.55, and a current futures
price of $10.30)
a) Calculate both the minimum expected selling price and maximum
net selling price of the fence.
b) Draw the...
Design a RAM circuit such that using two 64x16b RAM chips
constructs a
128x16b effective size memory circuit. Use the MSB of the
address lines as the enable line.
(Note: you will need to determine the number of address lines
needed.)
Write a program using c, c++, or java that have four dynamic
memory partitions of size 100 KB, 500 KB, 200 KB, and 450 KB. The
program should accept from user the number of processes and their
sizes. Then output the assignment of processes using the next fit
algorithm (specifying which process, if any, is block).
