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.
