26. CE is the logical combination of CE
27. The internal write time of the memory is defined by the overlap of WE, CE = V
28. Data I/O is high impedance if OE = V
29. If CE
30. During this period, the I/Os are in output state. Do not apply input signals.
31. The ‘X’ (Don’t care) state for the Chip enables in the truth table refer to the logic state (either HIGH or LOW). Intermediate voltage levels on these pins is not permitted.
