Question
Answer the following about this "brainless" microprocessor:
Can READ and WRITE both be asserted at the same time? Why or why not?
Can ROM and WOM share the same address? Why or why not? Looking at your circuit should tell you

Yes, READ and WRITE both can be asserted at the same time. Because in terms of the timing issues, the data on the read ports is available immediately after the read enable line is asserted, whereas the write occurs at the next active edge of the clock. Because of this, the same register can be accessed for both reading and writing at the same time. In other words, the read and write enable lines can be asserted at the same time using the same read and write address.
No, ROM and WOM can't share the same address. Because the most complex memory RAM has both the components for ROM and WOM and as READ and WRITE operations are separate, hence they can't share the same address.
