10. Answer the following questions about the figure below: A) The memory address is 20 bits long and is divided into 9-bits, 9- bits, and 2-bits. If the 2 bits are the least significant bits in the address under what circumstances will words at successive addresses be stored in the same column (if any) address MAR) Cl DI buffer register MBR) U512 All chips 512 words by 512 bits. 2-terminal cells B7 D7 GroupE Chip-A group-C- B8 D8 Select I of 4 Eroips 1/512 Bit 8 Figure 5.6 1-Mbyte Memory Organization B) If the 2 bits are the most significant bits of the address under what circumstances will words at successive addresses be stored in different columns? C) This system is a 1 MByte memory system. IfI want to make it a 4 MByte memory system how many additional chips do I need to add? D) How many more address bits would be need for a 4 MByte memory
