b. User wants to add 128k EPROMs and 128k SRAMs to a PC using the 74138 to decode the 32k x8 memory blocks (EPROMs and SRAMS) controlled by Y Addresses available start 50000H and another D0000. 1. How many memory block required from EPROMs and SRAMS? 2. Determine the typical range address of added EPROMs and SRAMs? 3. Determine the range of each memory block controlled by Ys?
