 Interface 256 k bytes ROM and 256 k bytes RAM ICs

Interface 256 k bytes ROM and 256 k bytes RAM ICs with 8086 MP so that the higher address space is covered by Rom and lower address space by RAM. The available chips are (64 k times 8) RAM (64 k times 8) ROM. a) Show complete circuit including Buffers and Latches b) Divide the memory in high and low banks. C) Calculate the address range for each chip. Attempt the same question by interfacing 512 k bytes RAM so that only the higher address space is covered. Use (128 k times 8) RAM ICs.
