User wants to add EPROMs and SRAMs to a PC using the to decode the memory blocks $($EPROMs and SRAMs$)$ controlled by Ys$.$ Addresses available start and another $.$ How many memory block required from EPROMs and SRAMs? Determine the typical range address of added EPROMs and SRAMs? Determine the range of each memory block controlled by Ys$?$ Design and draw the memory decoding using $74138$ circuitries in which the memory block controlled by Ys$?$
