Notes:  
1. The diagram shows supported (tested) synchronous state transitions plus supported transitions that depend upon the use of G.  
2. 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.  
3. Transitions shown in gray tone 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.
