Consider a system in which 32kb memory space is implemented using four numbers of 8kb memory. Interface the EPROM and RAM with 8085 processor. The total memory capacity is 32Kb. So, let two number of 8kb n memory be EPROM and the remaining two numbers be RAM. Each 8kb memory requires 13 address lines and so the address lines A0- A12 of the processor are connected to 13 address pins of all the memory. The address lines and A13 - A14 can be decoded using a 2-to-4 decoder to generate four chip select signals.

These four chip select signals can be used to select one of the four memory IC at any one time. The address line A15 is used as enable for decoder. The simplified schematic memory organization is shown.
