 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. interfacing 512 k bytes RAM so that only the higher address space is covered. Use (128 k times 8) RAM ICs.
