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.
