Question

Problem 2.0 Part A (0 points) Consider n 1 Gbit DRAM chip organized as 16 million addresses of words. Assume both the DRAM cell and the DRAM chip is sequare The offset coucateuate to form the meuvory address. Using the orgauization appeauch discused class, answer the following questions about the chip Express all anwwers in decimal number of columus colunun decoder required (e to m) type of required (m to m) uuwiber of uauxes required of address lines colunun aumber of address laes coluaus ofhet

Explanation / Answer

part-A ans::

-->No. of columns = square_root (1G = 230) = 215 = 32K

-->Column_decoder required (n to m) = 15k to 32K

-->Type of mux_required (n to m) 32K/64 = 512 to 1 mux

-->No. of muxes required = 64 muxes

-->No. of address lines in column number = 15

-->number of address lines in column offset 9

part-B ans::

-->Word_address lines for memory system = 27

-->Chips needed in one bank = 16 bytes/word / 8 bytes/chip = 2 chips

-->Banks for memory system = 128M / 16M = 8 banks/sys

-->Memory decoder required (n to m) = 3 to 8

-->DRAM chips required = 2 chips/bank x 8 banks = 16 chip
