Memory connection (cont.)
There is two 32 kb RAM
Problem: Bus Conflict. The two memory chips will provide data at the same time when microprocessor performs a memory read.
Solution: Use address line A15 as an “arbiter”. If A15 outputs a logic “1” the upper memory is enabled (and the lower memory is disabled) and vice-versa.
