Q$3(15$ points$)$ These problems will serve as a refresher for memory address space, capacity and range calculations you will need for the next problem. Explain your reasoning for the following: a$)$ Assume that the $4$ x $3$ memory given in the text book is available in a single chip. How many of these chips are needed to implement a $32$x$9$ memory system? What is the total number of D FFs used for this memory system? b$)$ Find the number of cells in a memory chip that has capacity of $64$ Kilobits and is organized as $16-$bit cells. How many address and data pins does this memory chip have? c$)$ Find the size of maximum addressable memory $($maximum capacity$)$ of a CPU system with a $24-$bit address bus and $32-$bit data bus $($in bytes$).$ d$)$ Find the size of the address space $($in locations$)$ of a CPU system with $20-$bit address and $16-$bit data bus. e$)$ How many D FFs are needed for a system with physical memory in the range $800$H$-9$FFH where the cell size is $8$ bits? f$)$ How many $8$Kx$8$ chips are required to completely fill the address range $0000$H $7$FFFH with physical memory? CPU system has $16-$bit address and $8-$bit data bus. g$)$ How many $32$Kx$8$ chips are required to completely fill the address range $80000$H $$ BFFFFH with physical memory? CPU system has $20-$bit address and $16-$bit data bus.
