The diagram shows supported (tested) synchronous state transitions, plus supported transitions that depend upon the use of G.
Use of “Dummy Reads” (Read Cycles with G high) may be used to make the transition from Read cycles to Write cycles without passing
through a Deselect cycle. Dummy Read cycles increment the address counter just like normal Read cycles.
Transitions shown in gray assume G has been pulsed high long enough to turn the RAM’s drivers off and for incoming data to meet Data
Input Set Up Time.
