A. Given a 16Kx4 ROM memory chip, Assuming the need to have one Control pin, one VCC and one VSS, Draw the smallest DIP package required to package this chip. Show all pins, signals names, and signals directions. B. Design a 256Kx16 DRAM memory using 64Kx4 modules (or chips). Draw the block configuration of the DRAM showing all required input and output signals. What are the sizes of MAR and MBR? How many modules are needed
